marker with a slight chalky feel to it (version 2)
brush is pretty blunt as well as slightly transparent. It also very slightly blends with other colors on the same layer.
when using a background behind art colored with this brush, I recommend creating an opaque, light colored slihouette behind the character / object art, as the background might show through otherwise.
brush can be used for sketching, lineart, and / or coloring.

character is still my OC sawyer :)
(updated version has a different texture)
