I can feel the vibrations, hear the humming electronics and crumbling stone, and see the light pulsing from where you've depicted it. This is a fantastic artwork. I just wish I could set it to wallpaper... Maybe a little time in CS4 will help.
The boss is f'ing intense man! But his armor is kinda misleading my eyes, his head/shoulders and arms are visibly turned towards the boss, while the rest (mostly because of the torso looking armor + the "cup", wich also leads me to assume the back of the knees are actually kneepads) looks like its turned toward the viewer
