Wicked, you done really well on this. I'm glad you kept it in that background. Nice and clean is how this should be done. The two tone colours, rims and front bumper mods are subtle and I think all that this car needed. I also think it's a very practical set of changes, that would be popular in the real world.
A few things I'd like to see changed, and that would enhance it even further imo: It appears that you have elongated the bonnet. I don't know why you chose to do this but I feel it makes the car looks stretched out of proportion.. I think the original dimensions were fine.. But then again you may have your own reasons for having done this (impression of widebody perhaps? increase the stance of the car etc..). Also I know this kind of has an impact on the following point I'm about to make:
May I also suggest that you center the car a bit better in the finished version. It always looks better when the chop is centered in the image, as then it forms the central focus piece.
Promoted you up to inter where you belong for this. I liked this chop, the base had a lot going for it. You improved it realistically and tastefully, and in doing so kept up to your name!
