You wanted critiques...
Ok, here goes... I thought the art was pretty good, not much animation though. What little motion there was seems to need a bit of work to smooth it out, make it look a bit more like real motion. The audio was a little overmodulated, bring your level(s) down a little & it should fix that problem. Now for the writing: It seems this was sort of a "just whatever popped into your head" type of session with a mic, seems like nothing really popped in there though. You might think about just taking a break from it when you get bored, instead of just ending it. A story of some sort would help tremendously, perhaps a twisted version of "Peter Rabbit", or even an animated version of your favourite dirty joke starring Dumb Bunny. Give your character(s) something to do & a reason to exist other than to take up space. Maybe give him a job, or a reason to go to the doctor, or a girlfriend, or something other than just standing there & doing nothing but farting once in a while. He can do anything: shoot carrot juice in his veins, boink all the girl bunnies (bunnies are good at this), have an accident with fire, take on a hunter, go fishing, cross the road, get used as toilet paper by a bear, etc... Use your imagination, the sky's the limit. I hope you find some of this useful. Regards, ZB
