I'm off to a good start. Completed my 100-a-day gesture drawings (takes about 1 hour to complete with pose rotation set to 30 seconds), a full value study based on Matt Kohr's tutorial (ref is on the left, my study is on the right; took me approx. 4 hours; still too slow) and managed to put in 30 Loomis face construction iterations.
The original size for the 10x10 sheets is 4000px and the vase from the value study is approximately 2000x1000.
Head construction requires a lot of ellipses, which is a challenge, since my hands are still wobbly with the tablet *argh*. More practice should take care of it. Anyway, not a bad start for this new year.
