To improve my grasp of human anatomy, I'm doing one sketch from a photo reference every day.

Same rules as before:
It has to be done in less than 1 hour, I can only use the one brush (Though I can choose which brush before I start), and I can only use black. No undo, no erase.

I'm not concentrating so much on re-producing the whole picture this time around though, more just trying to get correct looking human body shapes.

I've added a new little twist to the process and started making these into free commissions.
See my journal for more details: http://www.furaffinity.net/journal/1398814/
This time the photo reference and the anthro character to turn it into were provided by  amberli

Forgot to check the clock when I started this one, but I know it didn't take more than 35 minutes.
