Exaggerated poses, and lots of movement. I try to make my characters always moving, instead of standing still.
And I like to use song titles from the Metal bands I like as arc titles. And if I can reference lyrics, I will.
There's always an underlying sea theme for me, no matter what the genre, even if it's just a little, it's there, even the stars I draw are starfish.
Now I cannot unsee it in your characters 
You need someone in Cheburashka's costume 
and Gena's too, I guess 
I don't think being similar is something to be dreaded of. No matter how unique your series are, there must be something similar to it even by one element, and there must be another series that just make it pale in comparison. Praise the ordinary.
Okay then to answer the question, none of them are unique to mine but those are recurrent:
- Use of primary red color of different opacity for sketching.
- Wavy hairstyles, defined cheekbones,
men in dress, overall weird fashion. - Sweet, dainty, unsuspecting-looking but powerful and/or manipulative characters. Characters that are weak pushovers until they snap, yandere or yangire.
- Humanoid/human-appearing creatures whose true forms are far from human, or "humans" that are not fully human.
- Mundane can be cool.
- Characters that are suicidal, have inferiority complex, or parental issues.
- Hybridization (includes interspecies relationship)
- Cannibalism. Yummy!
I'd say my signature thing is my line style. I have yet to see anyone else who does it like me.
It's actually very simple: the lines are low resolution and anti-aliased. The thing is, that's not something they hand to you in most art programs (I guess it doesn't really look 'professional') so most digital artists would never get in a spot where they make lines that way. I'm not most digital artists, though. ^^
What gets me about it is that because it's so unorthodox, people seem to think it's intentional. :9 Like, if a beginner artist draws with really rough lines, you just say 'ah, they're a beginner' but if a mature artist who clearly has mastery of many techniques draws with rough lines, you say 'that's their style'. So people think this is my style...
But to be honest, it's not...like, I didn't really choose it. It's just a byproduct of my current process. If I was given a tablet and a bunch of convenient aliased tools to work with on the regular, I'd probably just go with those. ¯_(ツ)_/¯
Ahh! This is all really interesting, folks! Thanks for sharing with me!
I'm really intrigued by what people notice in their work like that, and how it develops. Some things we pick up ourselves, some we may never notice until a reader points it out, haha! For me, the burgers developed from being stuck as to what I should draw in my backgrounds, particularly the floors, they're always so blank and I struggle to give them detail, hence, oh, someone dropped a burger here, I wonder why. It invites introspection.... Were they drunk when they did it? How did they feel when they lost their delicious burger? Is it still good? Why does everyone seem to drop burgers in this universe?
tea. there's a lot of tea involved in my writing. I even named one of my characters after a flavor of tea (Violette).
Hmmm, I would say fluffy hairstyles, the good old small stripes in the nose and lots and lots of rim light details and light effects.
Also lots of close ups on eyes/hands to catch subtle expressions.
My characters tend to be expanded upon aspects of my own personality, So a few lines of my internal monologue will occasionally sneak into dialogue, sometimes without me realizing it. Narrator characters are especially prone to this.
Whenever I draw landscapes or grassy fields I love drawing overhanging, cylindrical rock formations 
If I'm making a large grass field I like to spread some red flowers across it to create some visual interest. As well as some particles and fairy like creatures close to the ground 
. Might not be a signature thing, but it is something I enjoy adding to create some more visual interest in some empty areas 
.
You can see these in my latest cover I made for my comic:
When I do background things like signs, I like to be as vague as possible. For example, instead of a “help wanted” sign it just says “help.” Or a street sign that just says “no” without specifying what you shouldn’t be doing. Just my sense of humor I guess :3
Ah, the burger thing is super cute! 
I don't write a comic, but I do write a New Gods novel that I make art for. I would say my signature writing thing is the usage of "gross" horror words combined with ethereal descriptions to paint a mental picture of the industrial hell-world I'm writing about. And for my art, definitely red cyberpunk cityscapes and alien/demon people. Oh and omegas lol! None of these things are unique but the way I combine them to write about something I adore is unique to me, I would say. 
Stellar moved through the murmuring glow until she was in a crescent of shadows. A hot breeze filtered through the area whipping Stellar’s hair and dress into a hallucinatory spiral. Beneath her, terrain groaned mechanically. She reached out and grabbed a nearby pole when the planet’s surface shuddered momentarily. Due to the geo-active nature of Apokolips’ internal structure, such disruptions were commonplace.
(from ch.13)
Demilunes clawed skyward; saliva made of darkness seemed to reach for her. Even to elites, the Royal Palace was a menacing zone. Stellar gripped the hem of her dress with sweaty hands. She hadn’t found Tilde and no longer had time to search. Stellar peeked at luminescent lava streaming near decorative towers. She visited the Palace many times before, but it never ceased to set her on edge. That morning was particularly sickening due to her nightly misadventure. Ambient pain enveloped her in layers of mental sediment.
(from ch.14)
I have three signature characters who always appear in every story. Sometimes, their appearances are more subtle than others.
A pun connoisseur? I love puns. They're getting more and more abundant in my comic xD Sometimes the audience can tell a bit more than we can. Perhaps a commentor has mentioned something that they feel is unique to your work?
I think my signature thing is how cheesy or sentimental my episodes and characters are because I tend to get the cheesiest ideas and just run with them. I feel like I am getting more and more cheesy as I continue to make episodes xD Another thing is probably the O-surprised eyes, I make those a lot, like more than the daily recommended amount on the prescription bottle kind of a lot xD
