Thanks for the feedback yesterday Anon. They're not supposed to look crusty, sadly. I'm trying to go for like desert tan, Marine style kind of look. I did black straps on the harness, and tried a wash. Not a proper wash but like a watered down paint.
Watched something on googles yesterday, and I think they're better than the last set.
Overall, I think they're just looking muddy, and my 'Tan' isn't white enough.
