In a bit of a hurry so here is the fast version of my long posts:
Paint: great, fits well with the style, looks really cool
Rims: Cool, but don't quite fit the style. Don't quite like the lips, feels very euro/german style.
Hood: Awesome, love the details, especially in the grill. Really nice design there.
IC: The shadow around the IC is to smudgy and to dark, define it more with pentool, and give it around 75% opacity.
SS: Really nice brush there
FB: sam as ss
BG: nice choice, but refs on the hood should have had a bit less opacity, can hardly see them.
Reflection: Cool idea, which should work on that floor but the reflection needs some blur. Way to sharp right now. Add some gausianblur... just a few pixels, and maybe some waves or something like that, just a little, to make it look just a tad uneaven.
Overall a very cool chop

Keep it up!
Cheers!
