Your style: No words, just how he looks most of time in drawings
Anime: I think I butchered it, I'm not familiar with anime
Chibi: Actually that's cute
Your old style: Um, so he looked different back then to his current design. This is the reason why he doesn't have a mouth.
Realistic: Nowhere am I familiar with rabbit and bird anatomy as you can see (The only semi realistic things I can do are horses and wings of sorts.)
