I have primarily been a 2D animator I also have also been working a lot on anatomy and drawing the figure for the last few years. I also spent about 8 of those 13 years working with more traditional 3D software. Add to that about 30 years worth of drawing every day.

My skills in ZBrush are something that is new but I can progress this quickly only because I have a lot of transferable knowledge.

I have actually been surprised at how good my sculpts have been, when I tried to use it before I had my 3D hiatus all my work was really horrible.
