It's been far too long since my last painting. This evening I managed to spend an hour playing with the Windows 10 app version of Sketchbook Pro on the Surface Pro 4. As a subscriber to the app, I get the full selection of brushes, which you are able to tweak. Through these settings I have managed to create an eraser which is the same shape as my favorite brush; something I believe to be so important in achieving a painterly finish.
I look forward to spending more time on it.
