I've decided to focus on the other painterly Procreate brushes for now - I notice time and time again that digital brushes designed to emulate watercolours tend to frustrate me because they come so close to the real thing - and yet refuse to do what I want them to. Better to work with opaque brushes, as I have no non-digital experience with those and can experiment freely. :)
Here's Rick, the brave postapocalyptic squirrel, in a wild mix of one brush from every Procreate brush set I have ever downloaded or purchased. XD (And those are more than should be allowed.)
Here's the process vid of "There is always light", too!
