OMG, I do that all the time. Once when I did it in a pub with a bunch of other people, this girl said to me, "Don't you know people who do that are supposed to be sexually frustrated?" and I was just like, "Oh." *continues peeling*. XD
oh gosh this is seriously freaky xD because I do this allllll the time AND I look just like the person you drew xD I'm guessing that's you? lol but I have bangs and the same hair color! But my hair goes down to my butt lol
practice makes mastery, also the "undo" tool is your friend, btw, did you knew that in paint if you doing a line and you don't like how is it going you can press right click while you stop pressing left click and the line will be gone?, i do that often until i get the perfect line.
