I like that orange and black color scheme Niclas, excellent job.
Would you mind a little constructive criticism from an old car moldeling fart to help improve your future builds?
Compare the model to the real car, fill in any body seams that shouldn't be there.
Check the nose and tail piece especially.
Color sand (wet sand with 1000 or finer paper) or polish out the paint to rid the finish of the rough sandpaper like finish. Then apply a coat of quality wax. I use Meguiars Scratch X (or Crest toothpaste) for polishing after the wet sanding and then Meguiars Gold Class Paste Wax, both available at Wal*Mart. A little goes a long way and the containers will last a very long time.
