Another practice chop.

Very good chop!
I like idea for body, car looks really crazy
I think background is too simple for this car
Good job

How's this?

This is really cool. The second version is definitely better. Love the air filters sticking through the bonnet.

There's a black line following the rear and roof part of the car, just use a small soft eraser to remove it. The body of the car is also yellow/beige but the new widebody parts are white. Unless this is intentional, use Hue/Saturation to either desaturate the body or add the yellow/beige to the added body parts.

As Daniel said, and one more thing, which I usually fight with too, the shadows. As you can see, it has a clear line at the front, so you can't use a very soft edge black under it, because it destroys the pic. It screams for sharp edge shadow.

Alright, Thank you
