good to see another southpaw in our midst.

one other suggestion...its not that im not a fan of masks, im just not practiced with them.
so in times where a mask my not be suitable and you need to detail around intricate edges---- use a larger brush than needed and use the history brush to go in and do the cleanup where needed. this allows for use of a harder brush at the edges. rather than trying to go in with a multitude of brush sizes and D/B while trying not to overlap your strokes.
