looks good, but u should try to move the car around the shots a little bit, dont alway center the shots. try to capture some of the backdrop. the pictures arent that dark, which is good but they might be a little desaturated. (unless ur going for that look). for the black and white shots, i strongly suggest turning up the contrast a little bit, itll look more convincing if you do so. and for the rolling shot, u can try the wheel cut tutorial, take 2 shots 1 with a fast shutter and 1 with a slow and chop the wheels over to make the wheel look like its spinning. as you may have noticed, the rims (during races) look really bad compared to photomode. keep it up man
