@wekanian Alrighty I'm back! Turns out I was a little more busy than I thought, so hopefully it wasn't making you nervous or anything while waiting for this little...kind of critique? It's not really a critique, since it's just legibility stuff.
Since this is scroll format and I'm on a tiny baby laptop I'm gonna read it on my phone, hopefully that was the way you intended, since it's a bit too tall to be nicely read on this tiny laptop screen.
One of the biggest things was onomatopoeia usage--which is the words we use in english to be sound effects. I get the sense that this may not be your first language, and so I don't want to get on your case about technical writing and grammar usage (I still understood it quite clearly, even if some of the grammar was a little off). However, with onomatopoeia, interpretation can go different directions, so I'll let you know how I interpreted them.
-In Ep 1 I think I read everything the right way and in the right order. It came off funny to me, so hopefully that was what you were going for, especially since this big egg in the sky is honking like a duck in the first panel there when it says "HONK HONK".
I will say the art is very clean and nice, and I would like to see more of it, there's a bit of copy paste going on which I don't think is wrong, but I think some panels just needed more redrawing on top of what was drawn in the scene before it to make more reaction and interaction in the characters themselves. It is episode one, so don't worry about it, don't redraw everything or anything like that, just know that I got less of an emotional punch than what could have been.
-In Ep 2 the crickets make the sound of "Cricket." This could be a humor thing, in which case, I like this joke, keep it in. but it could also be that you wanted the actual sound a cricket makes, which is a chirp. Crickets chirp. Confusing since you don't want to be interpreted as birds, but you can add more iiiii's to the chiiiirp chiiiiirp or you can always just say cricket because again, I think that's pretty good, although it is kind of incorrect.
-I like that you chose a big landscape shot for when it says "why is it still up there" in episode 2. This brought a nice moment of mystery and helped build that tension I think you're looking for. It's a bit ominous.
-There seems to be a period of time between when he says "Yeah I still have the book, do you need it?" and when he wakes up in a void--I'm not sure if he fell asleep or if he sort of passed out while on the phone. Maybe you want to keep that a secret right now in the way you're telling the story, which is fine, but just know that for me as a reader, it wasn't clear if he meant to fall asleep or not.
-After he gets a visit from his ancestor who says "child" he moves his head with a motion that says "SET" and I don't know what you meant to say here. Set doesn't really infer turning your head. Did you mean turn? (and I did get that he was turning just from the one white line, so it isn't necessary to say "turn" although you can.)
-I do get the vibe that he is angry and confused at meeting his ancestor, so that's good. Also, I liked the contrast between him being late and in a hurry to get to school, and then realizing that there was no reason to be worried because all humans are gone. Makes nice tension.
-On Ep 4, there's a scene where the small crying boy dissappears in a WHOOSH and at first I thought the background here was a decorative pattern--I didn't realize it was meant to be the ground. Perhaps if you included the thing he was hiding behind in this scene, it would cement the fact that this is a physical background and not a decorative one.
-The panel "I am just looking around if there is someone else other than me" is a bit of an awkward sentence, some rewording to make it more clean or clear would be better. There's a lot of ways to say this sentence and I don't want to tell you to just use mine, but saying something like "I am just looking around to see if there is anyone else other than me left." Is less confusing of a sentence.
-On Ep 5 I read the first panel as "Ye-Yeah" before "It's nice that you have a car, Vikal." This could be because I'm hard coded to read left to right, that and it's the first panel so it's hard to come from the right direction instead of the left.
-In Ep 6 when Vikal gets his stuff while still not leaving the bathroom, I was confused, but then I noticed Farrel is also confused--so that's good. I think you meant for it to be a mystery there.
-I like that we have a character interaction with Vikal cooking Farrel pancakes, it helps me like them more, and it shows that they're bonding.
-In Ch 8 the dark blue background with black text on it is still legible because of that white outline, but it's cutting it pretty close.
-In Ep 10, she says the words "HAA HAA" as a reaction to everyone disappearing, and when I see "Haa haa" I think of sarcastic laughter, but I don't think she's laughing. Is this heavy panicked breathing? I'm not sure what emotion you meant.
-In Ep 12 we see the word "Set" again as an onomatopoeia and I still don't know what this means.
-I like the introduction of Irina, especially when it meets up with our protagonist and we find out he has like a heebie jeebie sort of magic we were not aware of. It is a nice reveal.
Overall, there were some grammar problems, but I could still understand everything (that and like...a grammar critique is a whole other critique and I don't want to dog you for every time you misspelled something or used the wrong tense.) And I like it, you build something new nearly every episode, you're getting better at the art the more episodes we go, and you have an interesting world an premise. Good luck on the rest!
