hmm i really feel you should have done something to the car itself
also i can really see the old bg in the cars windows still especially in the roll bar area..
even underneith the bumper you can see the oilpan hanging , now its in the new bg you removed the part where you can see light undernieth from the bg but the bright line on the oilpan caused by that light going underneith is still there
i'm not trying to nitpick but the bg change is the only thing on this chop and so then you should have nailed that imo
better said due to no change to the car at all you really find yourself comparing them closer to find the changes and such things even stick out more
the toyota next to the golf looks in place and fine but the nissan micra behind it makes it all look weird there
if i remember correct that micra isnt in that particulair bg so you added it ? (stancenation pic) ?
not flaming btw just being critical on the things that are done , showing you so you can do something with the info
hope you understand my c&c motivation
