Not sure if you didn't see my reply on HF, but I'll ask again here.
Did you follow a tut? As I've found one, on how to make an ipod shuffle at exactly that angle.
Also many pic's on google, of ipod shuffles at exactly that angle and similar colours.

So my question is did you follow a tut? Or did you look at your friend ipod and drew it from your mind in PS?

I feel slightly offended by the tutorial question. I had a photo of the Shuffle open alongside to set the perspective and a few guides, from thereon it was eye- and handwork.
