a new exterior from me..
Modelling by a partner, rendering, materials ect. by me..
C&C please!!
Really nicely done. I think the sky could do with some contrast, its all quite bright. The only other thing id say is that the car material looks a bit strange (maybe need more reflectivity on the bonnet) and the edge of the pavement texture looks a bit off. Road texture looks a bit too tiled looking, some variation would be nice. Other than that, looks great 
other camera..
nice lighting feel, maybe it could do with some variation in tone, especially in the shaded areas. the only other thing that bothers me is the edging on the cladding. would it have a capping piece, rather than being open like that? Just being picky.
Good job!
really nice render, congratulations. I have noticed something in your scene that i have trouble with as well. Black glass in the windows. Have you ever been able to correct this as i am having huge difficulty.

very clean render. 
very nice. where did you get the audi model? looks like your having fish tank syndrome with the windows though. i find a good work around is to set the ior for refraction to 1.001 on the car glass then set the fresnel ior for reflection to 1.54.
very nice stuff…looks like you need corner trims for the corrugated cladding though
the corrugated material is very nice mate
Very clean and beautiful renders.
I love it
