Bmw Car
 

i was working on this car modeling a month ago and i try to render it now ... expecting your comments to improve the render

2nd view

It looks pretty good, though it looks like the model itself could use a little TLC.... It looks as if it's been rear ended!... No offense.

As for tips on improving your Renders...... well first we gotta know what sort of a set up you are using.
what type of lighting, and textures, and all that stuff.

yeah - what's happening with the rear? - it's looking a little bumpy. I think your shader needs a bit of work - it just looks like a blue shader at the moment. I would definitely change the color as well - that blue just seems a little too...boring :) .
