I like the skin, and I dont wanna be a PITA, but the A L P I N E font seems to have the shadow/emboss effect the wrong way (upwards) on yours? IMO the shadow shoud be under the text as the light comes from above, if you know what I mean...
On the other hand, no one will notice as long as you're in the lead..
Ross McGregor if you are going to look at the lighting / shadows - make sure that you don't click "Use Global Light" on the dialog boxes. If you do that, the light source for all lighting based layers/effects will be from a single point/ same direction.
That's fine on a flat picture that's staying flat, but doesn't help if you're painting something that's going to be wrapped round a 3d model/mesh.
For instance, you want the light coming from the right of the front "Alpine" to cast shadow downwards, but from the left of anything on the rear to make those shadows point down after the panel gets mapped to the vertical rear face.
