Hi Shnick, I think the stripes are too bold and lose the zebra effect. The vertical-ness of them makes me think of a llama. Can you try for a cartoon-ey look where I can feel the personality of the zebra. Maybe a full frontal close up of a zebra head. Your bold line work might work well in that close-up format.
Shnick #83 is strong, cheeky and fun. I like it a lot. It would be great to also see it with the eye looking a little bit back at us. A sort of mischievous twinkle. We really want that connection with the viewer.
I think I prefer #82 to the more jowl-ey #81. Success of these will also boil down to the mood the expression on the face conveys. Fun, confident, warm, engaging, connected are all things we're looking for.
