Welcome to Autemo
i can only see two major mistakes, the front wheel looks like its negative chamber (dunno if you ment it, if you did cool just next time the top needs to sit in the arch more)
and the front bumper looks matte, if your doing a black car then more reflections the better imo, black acts like a mirror, specially when its in a polished state like your chop, so try adding more reflections from the bg or steal as many reflections as you can from the original bumper. Other than that i cant really see anything else wrong except maybe the mirror needs more of an impact on the door, kinda looks like its just stuck on imo. Other than that good chop and keep up the practice
