We were talking on the Concept Art IRC chat room and the topic of "brushes" came up. Brushes for Photoshop, that is. And well, this is one reason I love frequenting the CA chat. The following links are sweet!

[HERE] - Some custom brushes Mike made for 2DArtist magazine.
Here's some sketch/doos, but I really should be working on the assignment at hand. ;)
