Yeah, honestly it looks darker in the pics. Had to go in and adjust for the bad lighting outside and it blew out a bit too much. I'm gonna step away from it for a bit then take another pass at it. The way I paint them, I can go back in and bring it back lighter by small shades.Very good work ...but to be super critical...it's just too much dirty.
It's a common problem and I do the same thing when weathering.....less is more.
Adding black to create wear is a valid premise...but too much black kills the effect.
