Great skill and level! Even i'm not in love with race-ready cars, like this. Especially be cause of "stiff-looking" interiors. But with such skin and bonnet view or something another - will be beautiful. Thanks for sharing!
Very well done skins mate :)
As the others said, you could create package for 8/4/2k res skins.
8K for amazing screenshots (doing some with yours btw), the other 2 for mp races acording to taste and end user's computer specs :D
Keep it up ! and IMO 5 stars well deserved :)
