Here is my Work in Progress on my infiniti version of the XRR, I really just made it up as I went. I used photoshop (which I don't know a thing about skinning), and most of it is by hand, I don't even know how to make curved lines, so really this is master peice for me. I'm getting close to the final stages and I want some public opinions on what to add, ie: sponsors extra details such and such. Maybe something else to fix?

Looks good for curves use the pen tool, just :google: for tutorials

As for ideas, IMO needs more race sponsors, You have got yokohama tyres so maybe a yokohama sponsors decal etc.
