Realistic Nidoran Male

A Nidoran(male) i drew, I threw in some rabbit like features for the ears and face.
Nidoran Male: This rabbit based pokemon are very docile and tend to be more nervous and alert than their female counterpart Nidoran(female). The sharp horn on top of its head can secrete a poisonous venom, the size of the horn tell how strong the venom is, this can only tell poison of the male Nidoran and not the female. Their ears have special muscles which allows permits them to move in any direction.
