I have LOTS of brushes in my stash of arts but most of them I don't use often because I have other brushes that are my favorites and those I use the most because I like the brush quality and they are fairly small so that is why I like my brushes unless if I am painting the whole canvas then I would use a bigger brush to save me time.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
