I work on many projects simultaneously. I find that this allows me to focus on a particular train of thought through multiple pieces. For example, I can get into a mode where I am building armatures, and do it on several pieces at a time. Similarly, I might then move on to creating sketches in clay for several projects. And then when I am being detail-oriented, I can work the minutia on multiple pieces at a time. Stepping back from each piece allows me to keep my perspective and not get lost in a piece, warping the proportions or character of the art work.
