Beat da veyron!!

This is a rendering I draw today. I tried to use the render-style from my older lambo renderings, but gave it some background and speed to create a racing scene between veyron and my lambo. well, the rendering is ok, but the feeling of speed doesnt work as i wanted. I think it looks too static and the background doesnt match with the cars either. but the first step is always the hardest, and its my first photoshop since many weeks, so its ok.
