One week and no comments? That's bad..
This chop is pretty cool. You did a really good job at turning it from red to white. I also really like the body modifications rims and background. Looks like you spent some time trying to get the perfect atmosphere.
There are some things I'd like to point out. first off the shadow under the car is very small and should be blurred more. pretty much just like your original image. You forgot to desaturate the windshield so it's still blue like before but it's in a very yellow environment.
The last thing is the intercooler and vents in the front. It's way small and should be much bigger. I'm also confused to why it's so bright. It looks like you put a white layer on top of it with a lower opacity and when you added a pattern to look like a mesh you just erased it from the white layer. I would have preferred if you just deleted it. You need to add some mesh back to the vent between the headlights.
Some pretty good work and most of the things I have pointed out can be fixed in less than five minutes.
