lol pretty shitty :(.
sorry. heres some critique.
animation: its bad. that is, where there was animation. most of these were just animated gifs to music. that stickman one was actually the worst. people dont run like that. so fix you walk cycles. i suggest studying someone or recording yourself walking and work off that. second of all, your tweens. they look just plain bad. you should know what to and what not to tween. that bouncing your head thing for example. you shouldve made the neck a seperate layer, and the head a layer above it. then make the head bob up and down. anyway. those are just suggestions.
the rest: yeah pretty shitty. especially that 4chan shit. that was awful.
so keep working.
