The brushes I tend toward are always changing and evolving but this is my current set and one I enjoy using a lot. These are all custom made or tweaked from default photoshop brushes. They focus on making hard and soft painterly strokes, blending, and sketching.They should all work in Photoshop CS2 and above but I cannot vouch for older versions, sorry
(please let me know in the comments if you are having difficulties)Hopefully you will find something useful among them
NOTE: These brushes are free to use and may be used to produce commercial work, but please DO NOT redistribute the brush set itself for profit. They have always been and always should be free for everyone. If you should ever see a website selling this set for money please kindly re-direct people here.
