for 3D, my class had a live model that did a series of 6 gestures. we chose one and would have to sculpt the gesture rapidly as we got 20-40 minutes of it at a time. while the model was doing other gestures, I tried to capture the other aspects of the model but..... I can't say I'm too happy with how this turned out.

Sometimes I like to caption my sculptures so that their sad short life is more enjoyable.
