These are the brushes i used in a little tutorial on some techniques i've been learning recently
Quick piece of advice, there's a flat brush that i love using but to get it flat you have to tilt your pen... i'm sure you'll work it out
If anyone makes any cool artwork with them be sure to note me and show me
Enjoy!!!
PS. these brushes will only work with Photoshop CS and above, sorry if your using seven or something

I don't know how many brushes are supposed to be ,but 4 of them it work for me in GIMP
