Cool skin.
Valvoline is one of my favorite options for car skinning.
One thing though....
you have something against "preview" picture for cars ? :)
Also, your "livery.png" image has got NOTHING in common with your skin. So, all in all, your skin is very hard to choose from many other. I'm not sure why do you do that and HOW could you miss this. :S
Maybe you should fix it.
But I give you 5stars, since these are small things that I can correct for myself.
Dunno for others though...
