Ok my review for your comic:
The art is fantastic, very distinct from other comics, i love how somooth everything looks and the colors look great. The charcters are constantly in perspective or comlex poses, there are absolutletly no complaints here.
The story is somewhat early to critique, since it's not done, but these are my thoughts right now:
It's mysterious, i have so many questions about it right now, i wish i could ask you every single one but i'd rather read the comic and find out. I'd say it's a bit "cryptic" right now, i don't know exactly what's going on. Charcters talk about thing we don't really know about, i'm a bit lost but that might be just me.
The world seeems very intresting, it's colorless, yet intriguing, i want to know what happened and why only the boy has color and how are they gonna return the color to the world. I like the middle east aesthetic (i think it's middle east but i might be wrong) and i like it's still distinct form real world.
The only real complaint i have with the WHOLE comic would be the speech bubbles. They always seem a bit big for the text, and the font you used doesn't fit the comic at all. Try making the text more circular in itself, like this:
Otherwise, great job and keep it up!
Here's mine if you want to review it, it's not great or anything and that's why i'd like to improve on it.
Jus a little note here, the art quality REALLY changes from the first pages to the newest ones along with charcter designs. If you want to review art, do it based on the newest pages.
