You are welcome guys! Happy to help out.
SBerry, you could install the tools and try them yourself. Brushes by themselves mean nothing, it is up to your artistic skills.
IMO if you're looking for realistic natural brushes go for artrage or new Painter, maybe even Krita in the future.
As far as pencils and inks go, I am very satisfied with CSP, and blending colors is just relaxing (when not working for 15 hours).
All I need.
