I gave this a try a while ago but my scanner wasn't working. It still isn't, but I took another shot at this just now and thought I'd resort to photographing my sketchbook.
10 sec from a couple weeks ago (crayola twistable crayons, woot)
and another 10 sec from today (new markers)
and then after this I tried 30 sec but somehow it came out worse ... maybe 2am just isn't the best time to practice this?
The first time I tried this, it seemed to devolve into stick figures quickly. Probably there's no quick fix here and I just need to practice, but any tips would be welcome.
(On the plus side, this inspired me to try sketching my new baby boy's face, and that somehow came out awesome, so yay.)
p.s. More drawing workshops please!
