I'm down! Is it cool if I share a panel? Mostly because this character has been pretty difficult for me to draw given the arms and I really want the anatomy to feel believable without destroying the aesthetic of the form, if that makes sense. He's based loosely on Vishnu from Hindu mythology.
For the bg I've been trying to find a balance between detailing and too much. I didn't want to put a lot into the bookshelf behind him because I didn't want to take away from the focus of the character, but I'm still on the fence about that sort of look.
Panels are cool! I just don't feel like constantly openings links, it's handier to keep everything inside the thread
I get that. You probably don't want this to turn into a promo drop thread, either. Lord knows we have enough of those, lol.
Thanks for the compliments, you're right about the low contrast though 
. I do think it works to draw attention to her face and arms, but overall it is on the darker side.
Hmmm for yours I'll focus on the lineart. I know you have most likely heard a lot about anatomy and perspective already so not gonna nag on you for that.
You can however, do more with your linework. Right now it is very simple, all the lines have the same thickness and it doesn't pop too much. But look at the examples here:
I plucked these from the web and they are relatively simple changes, but look how it changes the illustration! It allows you to leave smaller lines for the finer details while drawing attention to the general drawing with bolder lines. I think this is especially handy for your Gargoyle cover. If you use bolder lines for the closer building you can really whip up the illusion it is closer than the faraway buildings.
Can I ask what program you use? Cause Clip Studio has the vector layer which can allow you to change the line weight of your vectors
Hmmm I'm mostly having trouble making sense of where the arms connect. Like on the left side (from my pov) it seems to be the one shoulder on top and then the other two sprout from beneath that one, like a pyramid if that makes sense. But with the other one I'm not so sure. But maybe that's the hair covering up some areas and it looks fine for the most part.
The books however are a bit jarring. It feels like you drew (or pasted in) the books and then erased the lines in front while some of the upper lines remain.
If you are afraid the books will take away the focus (or any background detail for that matter), you could make the contrast high, like having a dark bookshelf will contrast a lot with his lighter body and hair. That could really make him stand out. I'd say play around with the value of the books. But personally I'd keep in some of the front lines of the books atleast. It adds more texture to the background that it feels like it's missing right now (in my opinion).
That's fair, I appreciate it.
Yeah, I actually drew out the individual books initially as a sort of base sketch, then for the actual background lines I just did the outline of 'em to reduce detail. But having the darker contrast might help, thanks!
Hmmm that's kinda tough to say, because sketches/roughs do turn out quite different from the final product.
Do you also have a finished illustration? I feel like I can critique more fairly based on that
Sorry for the late reply 
ahh yeah I remember this one 
I think the biggest thing for me that stands out is the left leg. Compared to the leg behind it, it looks rather short and stubby, especially compared to the length of the upper legs. I marked it with some lines, see what I mean? Now it could be that the leg is at a different angle but it doesn't seem that way judging from the orientation of the heel.
I think if the leg was a tad bit longer it would look even better 
These are wildly different drawings so I'll critique them each
First one: I'll give you the same advice as Stargazer, try to use different line weight on your characters. If you draw both the details and outline with the same thickness it won't nearly do the details as much justice.
Second one: even if you go in lineless, make sure to make a sketch first to define all the figures and shapes needed. The fingers vary a lot in size and thickness which tells me that there isn't a strong foundation for this drawing. If you make a sketch first you can always do the lineless art in a layer above the sketch.
(I'm not saying you don't make a sketch first, but it's what I think is going on here)
I agree with that observation. The line art is fine. I didn't shade the forced perspective of the foot and the calf/shins correctly in the colouring part . 
Thanks for the feedback, I see what you mean about the fingers, some of them look like sausages. I did use a sketch but it was a very rough one, maybe I should've done a proper one before colouring it. For the first image, what would need thinner lines? The stuff on the face, inner ear, nails, cloth wrinkles, and designs on the clothes?
