20 min sketch, pt 1

I'm trying a new warm-up/ training technique... 20-min sketch. Varying mediums... basically I start a timer...and have to get as much done in 20 min as I can... timer ends, I stop, and force myself to share what was done. I'm trying to get better at not getting so caught up in small-details so early on in my artwork, and trying to focus more big-picture on composition/ structure. I also get hyper-critical of my work and tend to not want to share until it's 'done and perfect'.

I'd love to see what others come up with doing a similar concept!
