I would like some one to help me by telling what shade of purple it is, or better, a template with the shadow layer

If you use Adobe Photoshop or another graphic software that eats *.psd files I can link you to this: http://www.lfs-gear.com/kitz.html
There is a shadow layer included. All you got to do is move it to the top and set the layer property to "multiply".

I've got the gimp and got the pro-kit aswell but it wont open. why?

@Sponge
They are a dark shade of purple,thing is, i don't know which

well, I dont know where your problem is. Take some reference pictues of the Prost and adjust the colour of the skin till it matches with the original. And please dont use full-value RGB colors.They'll give give your skins a comic style, which is I suppose not the thing you want.

Should i update my gimp?
