Some updates on the lighting and comping to blend Iron Man into the plate a bit more. I didn't render him, I just did a image sequence playblast. I used alot of masking and to add layers of dust from the original plate.
Im starting an Iron Man animation test over a plate I grabbed from http://www.gettyimages.ca. The rig is MYRONMAN by Joakim Palmkvist: http://www.creativecrash.com/maya/downloads/character-rigs/c/myronman_rig--2
This is the original model and backplate slapped together without any post work.
