I'm worse than useless when it comes to artwork, but after some banging around in photoshop this is what I came up with.
Other than the Nascade vector it's a total cut-and-paste job. The background came from Deviantart and the car was from some random website.
I blurred the car a bit and tried to tone the color of the car to the way it might look being lit in that environment.
Does this seem attractive to anyone but me? Any ideas on how to improve it (other than to toss it in the bin, develop some talent and start over from scratch)?
