try with different pose for the donkey, i think his pose from backside is not polite for customer.Maybe they will bit disturbed when they see your logo. So i try with different idea. Donkey in fat body holding big burrito.Hope u like it.
i like ur rendition. only thing is the donkey to me looks a little like a gorilla. also can you please adjust ur colors to be a litlle brighter. the top ranked entries have the color combos that i like. please try without a sombrero. thank you.
