Hey. Your original link is just a link full of P1 pictures. I really like the background you went with, very dramatic and has a really nice atmosphere. I'm not sure if your car is black or really dark grey. I think the body of the car is too bright and I'd play around with the levels a bit to make it slightly darker.
You could try to add a dark blue layer set to colour dodge. It should give it a cooler atmosphere that would go really well with the orange sky.
I'd also like to see a presentation of your work, tell us why you went with this car and what you wanted to achieve.
