Ok your comic looks be amazing and the characters are natural, the poses are not harsh, the synopsis is involving and makes me want to read.
The only thing that bothers me is the one page for chapter, if your comic were meme and small joke comics I understand, but your comic is not that, your comic has a story an drama and the fact that your comic is the one page per chapter strip the climax completely, and makes the story not become as engaging as it is.
But I understand that it is very difficult to make a long chapter every week, even more if you work or study and don't have time.
I did comics with "big" chapters i ended up erasing all of them because i had no time and i felt bad with them.
So in some cases it is better to make a page per chapter than to make a big chapter and feel stuck in the comic you do.
About the colors I have nothing to say, I just don't read black and white comics because they make me depressed but that's my problem and I have to deal with it~
Sorry for the bad english T-T~~
