9 Categories:
--- Basic - brushes I use the most. Most of my paintings are made using those particular brushes and often I use only those alone. Brushes from the following categories are just an addition and are used depending on the subject and stylization I work in.
--- Clouds - a few dynamic brushes to paint skies, mist and smoke.
--- Rock - perfect for rocks, ground and other rough surfaces.
--- Water - splashes and brushes with wet edges - best if used with light paint on dark surfaces.
--- Hair & Feathers - Well, ain't I a douchebag. I completely forgot to check the release document for most of the fur and feather brushes and now had to remove them from the set.
--- Plants - a very big set of dynamic brushes for painting foliage. Most of them are hand-painted giving pictures a very nice and unified look.
--- Details - all sorts of little things that add to the final image - seams, light effects, laces and trinkets.
--- Textures - yummy grunge and garbage that will make those flat surfaces look interesting. Scr\atches, wrinkles, rust, pores, stains - all you'll ever need.
--- Smudge - special brushes for blending. They give very interesting blur and displacement effects.
