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 phoenixdoll on deviantART, as part of an art trade.
She linked me to this stock photo: http://blacksockstock.deviantart.co.....-1062-95286381 for the pose, and asked for the character to be a calico cat girl.

The sketch took me 18 minutes.
Cleaning up the sketch and colouring took another 19 minutes, so just under 40 minutes total.
