Thanks very much guys, I really appreciate everyone's input. I look forward to doing it again soon.
Dropped Opacity from 70% to 40%. Thanks.
Robb's Brushes
This file is all the brushes I have. It's a big file and some are crap but it's everything. If you're not on Photoshop let me know and I'll post up some .pngs or Gifs. Always glad to give back to the community so let me know if you need anything else.
