I will upload digital sketches as well as some hand-drawn sketches in here. Most sketches are done in pencil, pen or on digital. I normally do the rough sketch of a drawing with red outline, the cleanup with blue outline, the line art in black, then add in the color. Here in this page, you'll just see the rough sketches, cleanup, and line arts.

Online sketches are pretty much the same as sketching on paper, it's just sketching with an online pen!
