Slow
While the ideas behind this were okay, the execution was poor. The movement in The Perfect Stick was very jerky and I stopped watching when one of the green stick men became completely transparent. The Saw clip was also waaaaay too slow, after staring at a screen with only a pair of eyes on it for ten seconds straight I gave up. The Mad World music video was better but the synch between the lyrics and the action was so out that it was ridiculous.
I think your artistic abilities need some work as well, although you don't have to be the greatest artist in the world to make a good flash, it just looked really sloppy and could be reatly improved by spending more time on each image.
