Hi. As you know, I've already reading your comics for a while. So I can try to say a couple of words about it.
Art:
I like your current art style. It is noticeable and draws attention due it is unusual. Your coloring technique gives it additional sharm.
But there is the thing about your art, which confuses me sometimes: many of your characters look too similar to each other, at least, from my opinion. Sometimes it is hard to determine their sex, because girls look alike the boys. I'd suggest to add more details to their designs, so they would look more diverse and distinguishable. But I'm not sure if this is objective point or it looks so just for me, because honestly even in real life I remember faces badly and tend to mix up different people.
Lettering:
It has not-constant quality. Some letterings look good, but another ones are hard to read. The thing you surely can do to improve your comics is to re-check all dialogues, texts etc and make them as readable as possible; also I've already suggested somewhere to add clear and readable translation to english everywhere where it is needed.
I hope that this was helpful! You gain my respect for originality and persistence in your creative work anyway.
