I think these are a nice temporary method to finish some current projects, but there will be benefits to learning how to render 2D in ZBrush with Step Curves and Outline. I don't know much about those yet. Still proud of these matcaps... they're not perfect by any means but it's neat that I went allllll the way to Photoshop and they kindof go along with my current illustration style. I still don't know what I'm doing.

UPDATE: The outline is actually part of the matcap. I didn't add an outline to the spheres, just pasted them in.
