I really like it well done, nice composition, (i think the two front fetuses should be more brightly lit though as they are the first thing your eye sees and they are kinda blacked out).
One question I have though is how come you have so much geometry in your walls? they are flat areas and so you can get away with one or two polys.... it would also cut your render times
