Well that was rather unrealistic
First of set the frame rate to 30 frames per second thats how all madness flashes should be. And almost all the moves were executed wrong. Think realistic do you seriosly think somebodys going to just stand there man they will obiosly react and try to run or shoot. The walking was also executed wrong now if you have the layers rightly organized then you move the feet up one little bit in every frame until you reach the top of corse then move it down in the same position but you might want to rotate them alittle bit to.
Overall pretty much unoriginal and choppy and plotless which leaves it boring.
Im sorry if I sound a little harsh but this is how people seriosly improve
