Cars and photos are really great. The post processing could use a bit more finesse. It looks like the cars were pasted into the background because the brightness/contrast between the two were separated so much. Also try staying within the lines a bit more when painting adjustments. You can see bleeding all around the cars. Just some constructive criticism.
