Audi R8 Background

Looks better now, add some life on to the car lights, when you look at the overal picture from the far away you can see some small composing bugs, just try to place the car a bit different.

You have some Vray light reflected in the back of that fence, that looks wierd.

Your Audi r8 text stands out you can clearly see the box borders.

Theres some grain on the front bottom Im not sure if that is reflection, overall add some subdivisions to your car paint map. If you look closely its not smooth, theres some grain going on.

The last thing is the overburned areas, your top of the car specialy. Not that its so bad but I would fix it you cant see the car borders and it melts with the sky when its like that.

I made a small change to your work [link] Not that its way better, but thats what I would be aiming for a bit more.
