I think it's safe to say you're improving very much! The Hydreigon piece in specific speaks to me. It feels like a really complete picture, not just in terms of practical application but in the sense that it really evokes an emotion. Same with the car piece. Both of those illustrations are telling a story to me and I like that much more than the ol' "character design" template. You communicate a lot through those works and I really think it speaks to your improvement as a developing artist. It takes a lot to make your audience
feel something.
I hope you continue to create. Just keep working working working and you'll get there!
