this image looked very dynamic from the thumbnail, so i looked at it. im glad i did.
only thing i see wrong with this is that the people seem to be jogging at a comfortable pace (im sure they're not supposed to look like that) but to fix it next time i would have them on the floor maybe with a dramatic *arm covering the eyes stance*, or maybe the ever popular *put hand out raeching like it's trying to stop something from hitting you stance*. Also, the guy in the far left doesn't look like he gives a crap what's going on.
as for everything else, wonderful job. I love the explosions and especially the robot on the left.
