Amazing piece! There is almost nothing I can critique about it! The flames look a little off and so does the hood. For the flames, try searching up some tutorials. The only thing I can recommend for the hood is to add wrinkles.
When I usually write reviews, I try to find some flaws, and I actually had to look at your piece for a few minutes before I noticed something!
Beautiful piece!

This is absolutely amazing! Whether it was intentional or not, I really enjoy the texture on the piece. I'm also 11 (just turned on the 30th of August) and I doubt I would ever be able to pull something like that off. The only thing I would change about the artwork would be the character's slant (many beginners do it, nothing to worry about - you'll grow out of it). As a fellow 11 year old, would you mind checking out my submission (my second post) and critiquing it? Anyways, good luck!

I love the color choice and the actual way this is drawn! The only thing I would change would be to lower the purple dot count.
