Depending what else is on the car's left (your right) I'd have gone to the passenger-side front quarter at around 18mm for an oblique perspective. I say this because:
- you have a very interesting light source (neon) but, in this case, it is best left out of the frame so you can perhaps be able to better compensate for the fluorescents to the right
- there'd be other cars (at least one that I can see) to make the background more interesting - actually, with the building to your back, I'll bet there's a road you'd be facing (slow-shutter light-trails?
)
- the 18mm perspective will help the background keep its distance and helps exaggerate the size of the car
- the oblique angle gives us both the opportunity to see that lovely engine
and the body of the car
and adds depth.
I hope this helps. Also, I have to say, I'm envious of the subject matter you have to play with, lol.
