I like the design of the bodykit, seems thought through and consistent over the chop. I'd preferred to have made the "mouth" angry instead though, like spun the middle hole upside down. Would have made for a more agressive look.
The brushing is pretty good but a bit matte. Seems that the car is extremly glossy, and you havn't quite managed to get the really bright tones in there to achieve the same glossyness on the brushed parts as the original. Also the shadow underneath the main hole on the fb looks a bit blurry, could have been just a tad more strict.
For the full look of the car also I think some white rims had been nicer. They do incorporate the color from the grill and various other pieces, but I still think white could have been cooler. But that's more of a personal thing.
Overall a really nice chop, and as you said, it's a bit old. Still I am looking forward to seeing more from you cause you seem to have a nice eye for the perspective thing, and I bet we can see some more elaborate kits from you in the future!
Cheers!
