Hi everyone. I'm new to the forums but I needed some help with cars. I made a (what I consider to be a pretty) neat render of a car -- my first one, certainly not my last though

. The only problem is that I don't know for sure what type of car it is!

I think it's a 2008 Audi S5 Coupe??? Help!
Here's the image (it's completely not done yet):
I'm plan on doing some more renders of different cars, hehe, so I'm sure I'm gonna need help identifying those as well
here's a link to my gallery of 3d renders (still in it's baby stages). maybe by the time you look at this it'll have more than one car posted
