Hey Si

Here you go. But this one is purely photoshop, no 3d anywhere.
Basically, I created the flat 2d shapes in PS using say a beige color, but of slighly different tones so I could work out where the light and shads were coming from and then for the textures used the blendmodes in the layers palette (screen, overlay or soft light) until I was happy with the way the texture was sitting, adjust the perspective as needed - Done!

I have got 3d mattes but Im afraid you cant see them until end of May (Outlaws Stuff)

Cheers
Jay
