Anatomy Study Sketch: Male Torso 2

A short sculpt, an hour or so spent. There's a few obvious flaws but it's better than no sculpt at all.
Experimenting with a 'chipped' effect on the dead ends, think it can work if done a bit better and clearer?
Will attempt to alter this soon, a more barrel chested orc version, so expect green!

Any good guides on how to get better quality timelapse from Zbrush?
