A pencil that became my favorite for sketching!
Examples of the brush at different sizes:
(It looks strange at a very large size, so I'd recommend keeping the size pretty small!)
The brush doesn't vary much by pressure, and the opacity doesn't change either. If you don't prefer the default settings, you can always edit the brush to your liking! Here's what the default pressure range looks like at 50 px:
You can use this pencil for anything of course, but I prefer to use it for my rough sketches, as I find it helps me keep things loose and messy. That's pretty much everything, so happy sketching! :)
