Get them from my site here:[link]
Free to use however you'd like. Commercial, non commercial, have fun. There are a LOT of watercolor brushes in these, haven't count yet but they're a good variety for you!
You may NOT redistribute these outside of DA, or anywhere else on the web, OR sell these brushes.
These are hi resolution water colors I made myself. They're over 900px and the biggest one is about 2000 px but I can't be too sure. Enjoy and have fun with these
A second watercolor set is coming out soon!
