1. For the reflection on the car : I selected only the body panels and spray painted it.
2. For the reflection (mirror effect) on the floor : I cut and pasted the rear wheel and leveled it with the front wheel. Also cut and pasted the front wheel and corrected the angle as the wheel was slightly turned in your orig photo. Once you have a full side view and the base is leveled, the reflection part is easy.
3. Overall lightened and cleaned up some areas, including punching out the windscreen with a white background - since you're supposed to be in a 'studio'. :bsmilie:
