Looks really good! The only thing I'd change is om the green the green by where his ear is, it isn't a curve so much as it is a square. It's like a shadp curve
In the lighting, which in real life it wouldn't be so defined and would be more rounded since it's from a flare and not like a lamp or flashlight. I would also have the lighting over all of his head instead of just the top part unless theres something that's supposed to block it out, I might be missing. Overall though I really love how it looks! I really enjoy seeing art with bright colors and everything. Keep it up man!

Yeah, you're totally right, I'll keep that in mind for future drawings. Thank you so much for the feedback!

No problem! Happy to help!

Very cool!
Good job x3

Thank you!
