Not sure buddy,
The whole bottom of the car (side skirts, bottom of the front bumper, rear bumper too) was just dragged down and some warped wheels thrown under it...it doesnt look slammed it looks messed up...the reflections are a mess too...the side skirt has some (in the correct direction) but nothing on the rest of the car! This is a major reason why i highly HIGHLY recommend against using a studio pic as a base when u want to place it on a bg thats outside...you loose all reflections and light sources making it look seriously fake! The front headlights are a "hate it or love it" thing so im nobody to judge but the execution is lacking quality...this is especially evident on the large image...its all very blury! As i've already mentioned the rims are warped...i feel that they are too oval in shape...also they dont match the contrast and lighting of the car or the bg! Something to look out for as well...
I'll see if anybody else has something to say before i give it a score but i'd say that this to me is around 4/5 points!
