Please don't get me wrong!! You're doing an excellent job. The only issue I have is when you look at the whole car from the side. The lower rear end of the rear panels are much higher than the lower part of the front bumper (looking at it from the side). Your work is really excellent so my critique must be taken with a grain of salt. I have also made major modifications to car bodies and I realize that it's difficult to make major changes when you're getting close to the finish line. I think that the design of the front bumper is really, really nice. Typically when a car is designed the lower edge of the front end is basically on the same line as the lower end of the back end (compensating for rake of course) . If you're happy with the end result then that's all that matters.
Please don't take my suggestions so seriously, I'm only trying to give you another person's prospective.
