To be honest I mostly draw laying down on my stomach, habit of mine, I even ink traditionally laying down like that @_@ .
But when I'm sitting and drawing I sit like Zelkats hahahahaha, only that I look at the paper and not at a laptop/pc, ahahaha I look like a little monster, my face so close to the paper and my back all hunched oo.oo .
It's so bad for me, I need to work on that 8_8
