As I can't draw for shit to comment on technique would be unfair and ill informed.

HOWEVER, I can say what I like lol. And I like this. It's immediately expressive. The colour palette works well and could be off putting if not applied well. I like the thick outlining, it helps contribute to the comic/cartoon aesthetic. The shading seems consistent as does the lighting perspective. Something feeds a bit off with the right arm, I think it should be straight rather than curved. That is all I can point out.

It's a 5 all day, it's cool seeing you develop overtime. Keep it up.
