I randomly wanted to make a base for these guys because I felt like designing some later so I needed the base, I figured I'd make it an editable though in case you guys want to make some as well ^^
Do whatever you like, just don't remove my sig and claim the lines as your own (you can move the sig about just keep it on there somewhere)
I use pen settings of 100% opacity, 30% smoothing and size 3. I press very lightly with my pen though so for most people size 2 will probably get you the same result.
