Not much done, but I like what you did. Especially to the front. I didn't even see what you had done at first, just that there was something rawer about the car! HAd to really compare to see, and that's cool. I also like what you wanted to do with the picture, but it just didn't come out that well.
First of there are lots of stuff left where you have brushed. For in stand in the grill where you removed the mitsubishi emblem I can still see some blur and pieces left on the fb. Easist way to fix this would probably be to take a brush with low opacity and just go over the area few times. The same sort of error is reoccuring in the main hole in the fb where you have made the hole bigger. You can clearly see a line there in the hole on the cars right side. Same sort of fix would work.
LIke the wheelnuts on the rims, just maybe a bit to lourecent. Don't really like the things you have added on the second version though. The smoke on the tyres is semi-correct.... it's in the right direction anyways, but needs a lot more work. And the headlights don't look very good, a donor to start with and then follow the tips above.
Just keep chopping!

Cheers!
