Hmmm no, never need to pee or anything, but I just start drawing and try to do something as fast as I can. I will not go longer then an hour with a speed painting. It is just something I do some mornings to warm up for the day.
Totally cool! And in 10 minutes?! Jeebus... I really like the use of overlapping "paintings" to give it that corroded and hand-made texture. Do you make those yourself and then scan them, or is there a site to get free-to-use downloads of that variety?
