Windows 10 Anniversary Update introduced the Windows Ink Workspace, a feature for stylus-enabled tablets (like the Surface 3) to make notes on screenshots, make sticky notes, and in this case? Has a very basic, quick-and-dirty sketchpad.
Having grown up during the 80’s and 90’s, I remember eagerly devouring Dragonball whenever it was available. If a friend came back from Japan (or more likely, a friend of a friend), there’d usually be a VHS tape full of the anime, movies, whatever. Feeling a little nostalgic, I decided Goku would be a fun character to sketch out. I really should’ve had reference for Goku. Totally from memory, but not right.
