2 promising wips so far.
The Black civic is looking good, but looking at how the lights is falling down through the bridges, I would flip the background so the lighting is correct
Good to see the new background working out, 3 things to improve:
-Make the 2 seats inside darker with a bit more contrast.
-The grill of the car is very blue-ish, remember to lower the saturation of the blue.
-The front lip is colourless and low quality, just use a smudge tool and lightly blur the parts so it becomes smooth, and brush some colours on the lip.
Good luck!
