Hey awesome job. This is good. I like the angles and the direction of the animation. I really like the extreme perspective warps although it lacks a certain subtle drawing cues that make it look like a stretch and not a drawing mistake. for example the cat's walk cycle loosing and regrowing his foot with each step rather than foreshortening. Another thing that bothered me just a bit is that you went a bit overboard with the airbrush at certain parts(14-24 most notably). Now I'm not going to say that airbrush never works in an animation cause I'd have too many counter examples to ignore but I would like to say that it's very easy to go overboard/do too much. Now I ain't saying to limit yourself to cell shade but at the very least try to make sure that the brush strokes aren't visible. One last bad thing I wonna point out is in the skin growing back on the body section I feel like (even though it would have taken a lot more work) adding some shading on the strand would have made it look more like strands and less like paint being applied on him.
Aside from these this is a really well done animation and I absolutely loved the ambition, the cat head, and how much it felt like things are physically interacting with one another. I actually wonna emphesize on the last one. I'm seeing alot even professional animators that can't make things look like they have any impact or physical touch. THis is something really great to have and I think you did a really good job with that. the landing the dirt, the cat grabbing the person. it all felt right and hitting. So great job.
Hope this was of any use. Great job and keep it up!
