The closer I get, the more realistic the results. Below is one I did a year ago at 'normal' range:

Although I'm going for a more realistic concept, I still take liberties with what I see. For instance, the pipes on the one I'm doing now were done with a 3 or 4 shades gradient rather than pulling up every tone and shade in them individually. On the other hand, I used a gradient on the rear wheel when it wasn't necessary, which is giving it a more 3D appearance than the original shows.
