hmmm so its not so much using the same brushes over and over but using diffrent techinques with filters to achieve the appearnce. I guess I was sorta on the right track i been playing around with dupilcating layers and playing with layer styles maybe play with hue/saturation features.

But yea these are the type of tutorials i came across when doing a search just never connected uses techniques in those tuts to try on brushes. Still I like to see tips and techniques other do so hopefully more will add to this thread so we can all learn something new
