It's not a bad chop at all, the few things I would fix are:
The shadow under the car at the front is too dark, and should flow more to the front wheel where it touched the floor. The hood looks quite desaturated (no colour) but you could almost get away with it in this background as it's not too colourful. The wheels have been done nicely and I like them. I'm glad you didn't go overboard with any mods, that's a common thing that new choppers do.
Keep going and we'll look for an improvement.
