Wow .....these brushes are almost real
I have been experimenting with the new dynamic brushes in Painter 2016. In particular I have been using the brushes created by Jeremy Sutton of PaintboxTV. If you are a member of this site you not only get great tutorials and news about Painter but have access to the custom brushes that Jeremy creates.
I am impressed with the marks and expression I have with the dynamic brushes in particular.
Since pictures are worth a thousand words, here are my first two paintings created with these brushes. If you get a chance give them a try.
