http://www.furaffinity.net/user/zakarifursuit/ and me's project completed.
(Yes zak, I'll finish the last one next week :P Loads of non-furry photos to process :P)

Shot on green screen and composited over a beautiful stock image. In order to make Zak sit in right, feet shadows were added, diffuse reflection of the suit on stone, plus occlusion of the arms against the doors. Background was gamma'd down to match Zak's photoshoot levels, and contrast tweaked for both to get a proper match. A final tone curve adjustment to give it the "film" look.

Sadly, I think most people will not be able to see the proper version as all my output is targeted for print; it's rare to find another non-photographer (or even a photographer) with a color managed browser and viewer :( Some furs at the meet yesterday will have seen the lovely print - as how photos should be seen :D
