Haha - I tried something very similar with the bg when I attempted to chop this - you've done it much better than me though (probably why I gave up)
As for the chop it looks pretty cool, i do like the design, and surprisingly, the continental gt front looks great

The murdered out look is also a pretty sweet idea, just not sure it's quite perfect
A few extra tips:
- The black paint has no colour at all to it now, yet black paint reflects more colour than most other paint jobs (except chrome). Try and add some hue back to it in areas, like a reddish yellow hue on the first chop to the sky areas, to suggest the sunset atmosphere
- Rear rim needs to be narrower, that's all dude - I think you'll have to find another donor
- Only real problem with the second bg is that the car has daytime reflections, the background night time ones. The solution to this I found, was to make the sky a lot lighter above the horizon, so it's kinda sunset, then the city lights would still be on, and you can have the best of both worlds. You may also have to brighten the black areas of the city too
Overall though, cool chop dude

Keep it up
