You gotta stop with the fake HDR stuff, man. Everybody and their mom is jumping on that fad. If you're going to do it, do it right, with either 3 exposures or a RAW image, make it subtle instead of overprocessed, you'll be more pleased with the result.
Beyond that, the shots and angles are good, and you're making good use of the lens' focal length. You could work a bit on exposure times, the pics do look darker than they should at that time of day. You have a lot of good light available to you at and right after sunset. Make use of it.
For example, this was taken probably a full hour, maybe a little more, after sunset, and I managed to get my car about as light as yours while you were past sunset by maybe 10 minutes, 15 at most:
Regardless, beyond the overprocessing, I like what I've seen so far from you, keep it up.
