It's great that you have such great animation. I was turned off by the toplessness. Why didn't the rabbit have breasts? I'm pretty sure she was female. The funniest bit was probably the credits with how he had the hole in his body. Both types are nicely done.
I liked how it was just one style and then another. It didn't change much, like I believe the last one. The colors are wonderful too. You can just imagine the other style in your head. It's quite creative again.
