Simply awesome, I love this style! He's very cute.

Very interesting, a few things bother me but the ink sand paper lines make this dense and mature...character speaking. Its like added detailign to the vigor and wounds, if not skin of the character. I personally think the character is a bit to skinny, maybe thats just the design but many things of him feel like they may be hard to get, or work with.

The shoes are very small, when I personally think of a rabbit, they are small, round, and sqauish forms of much fur and soft tissue. But given this is a punk aesthetic character you may have been going for a rogue BLs or tank girl style which means more differentiated body types. The shoes feel more simple and soft compared the rest of this character, like they are spotless. Maybe that's a detailing thing.

An I thought that was a cigar in his mouth, a savant with explosives and spunk. Oh boy thats a chemical disaster indeed. I feel there could be some more detailing on the body, it feels personally to simple with how complete it looks already. Dunno why but the idea of boxing came to my mind looking at this.

Critique - I only pray you keep your distinctive style and do not comform
