oke wizard,
I have seen those screenies and you made me wonder what the heck is wrong with your LFS settings. The reflections are horrible. Did you use Lybce his reflection pack ??. If so you did something wrong dont no what though.
Back to your skin, hmm what can i say. Try to aling the shape accordingly to the shape of the car. For instances, the fire on the site of the car. It starts at the door. If you start were the wheel arches are it looks more natural.
The same with the shape on the bonnet. Its starts in the middle of the bonnet which gives okward viewing due to the first bit of the bonnet starts at the front. If you can align thos things more it would look a lot better.
But firstly get that reflection sorted, that really looks overexposed.
