Character design
You're pretty good with character creation & design!
The lines are very defined and clean. Style is consistent. Shades and colors are well chosen.
I saw a few of your other works, and I noted you don't draw a background for your characters.
If backgrounds are not your expertise, I think you should practice drawing backgrounds. It would allow you reach a new level in your work, drawing the characters in the context of an environment.
Just my opnion.
