Much better Carl, better size for sure. I see some random pixels, just be sure to connect 2, 3, 5 and so forth of them. The shapes your looking for reminds me of "stairs". Keep it looking random and after you clean up the "masses" by squaring them off more you will have it I think.
Believe me once your done and happy with the camo it is a very satisfying, and you will never want to do it again (just kidding). Look forward to your progress-
