Good stuff mate, really liking the mods on the 34!
Just a few minor improvements to be had.
-The car is sitting a bit small in the background, I would move it up a bit and make the car bigger
-The rear wheel looks off, the dish on the rear wheel is so bit making it not fitting and make it look like its turning. So I would copy the face of the wheel and stretch it to cover the dish a bit So the face of the wheel sits a bit more simialr to the original image.
-The back shadow is a bit high, so I would shrink it down a bit
All just my opinion so I could be wrong
