I was asked by someone to make a downloadable file of the brush set that I use... so here it is!
It's for Photoshop, not sure which versions it'll work with but i know it'll work for CS as least.
All you have to do to install them is go to your brushes window, click on the arrow in the top-right of your screen and select either load or replace brushes and then select the file you'll download form here.
A hefty portion of the brushes in this pack I didn't make myself, and I'm not sure who did them originally because I lost the original brush pack files in the great wipe of my laptop.
I know that they are all from artists here on DA, so you can find more of their stuff by searching "photoshop brushes" here on DA. <3
