The few textures I use are from cg-cars.com, except for a couple of opacity maps for the windshields and logos etc. So you can get them from their forum.
All in all a very nice studio setup. Just some points that poped to my eyes:
-The seams seem to be inconsistant. Some seem a bit “bulgy” (esp. rear-end of the rear-door and the trunk seam)
-It could use some more light. Esp. for the tyres and the licenseplates. But also the whole front and rear seem to get kinda “lost in the dark”. Giving these spots a little more light would also make the siloutte stand out more on the black floor (wich i´d rather make a tad brighter to have a slight feel of shadow to make it look less “floating”. Given the brightness of the reflections on the carpaint i´d expect at least a bit of light to hit the floor)
-Rims could get more reflections to show their actual shape. As currently the front surface is almost black on the spokes. Looks a bit as if they would have more spokes then they have on first look.
-There´s a rather undefined “dark area” on the front of the hood that somehow disturbs me a little
As said all in all a very nice studio setup and a nice model too!
