Thanks, and thanks.
It only took one day for the original (painted background one day, let it dry, and put on all the black the next afternoon) but this one took several days. I "washed" on many layers of transluscent color (really thinned normal paint) to give it some depth. The problem was all the rain we had made the humidity about 100% and dropped the temperature, so it took longer to dry between layers. This one took about five days, when it should have taken 2-3.
P.S. Most of the grunge is semi-random, with strategic lines placed with the edge of very thin cardboard. If you look at the lower right side where the two lines stop short of the edge, you can see the thin lines I am talking about. Like I said, the picture sucks and doesn't show the depth and fine lines at all.
