I'm really enjoying the 'Evacuation' series MJ, although the first one is still my favorite; something about those bunnies being launched in to space just makes me smile :)
I'm not sure if the 'floor' is too bright or too expansive on the last one. It keeps pulling my eye to the bottom of the page away from the figures, especially the pilots. May be add some simple foreground shapes (boulders and so on) to break it up a little?
