So, I'm not sure if this is true for you guys too but one of my favorite things to draw when I'm just sitting around and wanna get the stylus moving is myself. It's easy and doesn't require a lot of overthinking and that's nice!
I'm not sure if my choice of subject matter is because I'm some kind of huge narcissist or that this way I won't offend anybody but myself if I screw it up heh. Probably both.
Also for some reason I generally tend to draw myself looking grumpy or annoyed. Lighten up, self!
