Everything for Rudolph was taken from the source image. I used the transform tool to morph the pieces into the shape I wanted.

I'm sorry that I didn't make a more detailed sbs, but everything I do is really repetitive. Every piece of the image gets the same layers. A blank layer set to normal and painted on with a soft 5% black brush for shadows. A layer filled with black and set to color dodge and painted with a soft 5% white brush for highlights. I made the rivets and lines with a bevel layer style with the pen tool and a small brush. Thats pretty much it. black brush for shadows white or colored brush on color dodge layer for highlights.
