Very nice! A minor thing, but I think you could push the contrast in the bonnet vents, and make them a bit darker in the deepest parts of the recesses. Out of the whole thing that's the only element to look 'painted on', otherwise it's absolutely fantastic!
Fantastic work! Really nice texture on that paint! And it looks very realistic! I think that reflection on the hood from the background is a little too sharp and visible for matte.. But maybe that's just me Great job!
