imo the quality is good , i know its a little hard to find a bg to fit in this , with the same lighting and reflections , but the lambo is prety awessome , liked the design , some damages on it will be nice huh?
To me it looks like the car is sitting too far to the right, it looks like it's on it's way into the wall on the left side of the pic. But the design is awesome, although the sideskirt should be a bit more chunky as Mark said. Apart from that - great work!
The overhead lights of the new bg are better imo. It'll give you opportunity to do really cool reflections on the windscreen and body of the car. Look at Maza's profile and see his lambo refs http://www.autemo.com/profiles/?id=maza bright glossy refs like that is what u need
