This is just a random thing I thought to mention. Pencil tool isn’t really for sketching. It’s set to basic brushes for a reason. It’s more for making lines. If you hold shift while dragging up or down you get a perfect line but it you click then click a point in another direction all while holding down shift you get a diagonal line. If you do this with the pressure brushes even with a mouse you WON’T get a diagonal line, at least not one that’s very visible. I use to think that feature was excluded from photoshop elements until I actually found the pencil tool.
I watch some youtube videos on drawing now and then and a lot of people seem to use the line shape instead of simple click+shift+drag or shift+click+click with the pencil tool. The disadvantage with the shape tool is rasterizing and merging all of those lines and cutting and pasting. If you go to window>> guide you can then see a ruler along the top and left side. Combine that with using shift instead and you can measure out your lines like you would with a real pen and ruler.
This method also works with GIMP and a few other digital art programs.
