Dude you have outdone yourself this time. What did you apply that stuff with - a broom? Haha! Just kidding - I know Herculiner is supposed to look rough like that.
I think the straight lines are what's bothering me. Everything else on the VX is rounded. It was built before the angular, stealth fighter look became popular. If you could find some Artool stencils/templates with a tribal pattern or some cheetah spots or something you could add them along the edge of the black to break up the harsh line and blend the black into the yellow a little better. Yeah, that's it. In fact why don't you do the whole village and pimp the entire thing out with cheetah spots... It's already got teeth!
