Five very digital looking pencils! :0
I've been experimenting with using spray pencils with no anti-aliasing, with varying degrees of opacity, density, & particle size. Here's 5 I came up with that I think are fun to use. :o
Don't be afraid to adjust the particle size or have the particles change with the normal brush size, make sure they're comfortable for you!

1. Pixel Pencil - Default Circle material. Feels the most like an actual Pencil. The particles do not scale with the brush, so the larger the brush size, the more of a spray it becomes. It gives an interesting texture when shading.
2. Pixel Pencil Square Light - Has a square tip. Crunchy & changes opacity & density unlike the other square pencil. Particle size increases with brush size.

3. Pixel Pencil - Equal Particles - Round tip. The particle size increases with the brush size. It is darker & harder than the Pixel Pencil in pressure.
4. Pixel Pencil Light - Round tip. A lighter variation of the Pixel Pencil, cozy to draw and shade with.

5. Pixel Pencil Solid Square - Square tipped. More of a pen than a pencil, this is the most "pixel art" of the pencils with no changes in opacity or density, only in particle size & particle density. A good pencil for challenging yourself or to only draw in monochrome mode.
Stroke examples, the numbers the same as above:

Thanks for reading, hope you have a nice day :D
