Iron Man hover

First of all, thank you Keith for inviting me to participate!
Sketched this on an oversized sketchbook then cleaned it up and coloured it in PS CS4. I didn't go with any reference, I just wanted to see what would come out of I drew Iron Man just out of my head.
The gray version is a simpler variation of the colours I used before, a little fun to create a War Machine like colour scheeme.
