You mentioned "cleaner" and I'm sure you mean in the execution of the build but if you don't mind me saying, I think weathering of this one would go a LONG way in it's overall appearance.
It would definitely cover up some of the aspects you're less fond of. Mis-cuts, not so straight detailing, and other small goofs be hidden well behind a layer of dirt and oil build up. The panel lines are a bit lost in the main body with it so "new".
Just a suggesty but a great success either way on a first try!
