hmm its alright but it would be better without the blinding contrast also its kinda plain at the moment, maybe throw in some nice c4ds/sparkle brushes or some displace?
the bright orange and the dark red dont mesh at all imo id try to use different colors...maybe make the car blue and go for a blue and white or something like that. blend the back of the car in with that c4d an it would be solid
The car render isn't really blended all that well, and the tag is pretty dark. As mentioned above, the amount of contrast kind of kills it. A couple touch ups and this thing could be really good.
