Here's my model 2 SNES repaint.

I was wanting to use the same color scheme on a model 1 but, I haven't had the time to do so... perhaps someone else will give it a go?
I've found when taking pictures with a digital camera (especially shiny things like consoles and other game stuff) It's usually best to disable the flasher.
As far as the yellowing... I haven't heard of a reliable way to restore the SNES bottom. Also I've heard that vinyl dye works well for coloring plastic cases... it actually soaks in so it won't flake, scratch or peel off like some paints do. Then there's the Krylon Fusion which works rather well.
