A simple set of inkers
This is a simple pack, but I also have some fancier pens on my gumroad at saturnsday if you need some natural looking brushes or hatching brushes. :0
Each pen is a smooth, basic pen, made to be comfortable and easy to use for most styles. The main things I suggest you adjust are:
- Angle - If you are left handed, change the angle or thickness to point the way you write. I'm right handed, so adjust to your liking.
- Density/Opacity Pressure - if you like thin, wispy lines, apply density/opacity pressure.
- Stabilization - My default has speed on & somewhere between 0 and 10, go ahead change it to your preferred setting.
- Tilt & Rotation - My tablet supports tilt, but doesn't support rotation. If you hate tilt or hold your tablet at a different angle, adjust it or turn it off. If your pen supports rotation, turn it on if you like it. :)
All pens can change color, and can be used in monochrome as well. I did several different types of strokes to try and demonstrate how they feel since pen feel is harder to explain. When you test a pen, try to draw shapes you draw a lot (like hair, flowers, eyes, noses, curls, cats, etc.).

I'm a fan of speed pens myself since they're close to what I use in real life. If you don't like them, feel free not to use them. :)
I also included 4 different pens for "filling" an area. If you have a big segment of solid black, you can use these to fill it in.

They mimic the look of markers that can make varied, dynamic lines when shading big sections of solid black. You can also fill in a solid black area with the fill tool, then use these to add hatching for shading transition. The bottom one is great for abstract background shapes as well.
Here's some test lines I did. I did them fast, so they have no consistency, oh well. Hopefully it shows a bit of how different each brush is.
