Thank you! Rock texture is always tricky for me. I never feel that it looks right, and I tend to overwork it. What I did here is draw a few versions, and I kept the one I liked the most, and set the other two to overlay on top, reduced their opacity a bit, erased here and there, highlighted over the whole mess here and there. I haven't figured out a great method for doing rock texture yet, I feel responsible for each tiny particle, which is ridiculous. Probably need to just relax and study more rock references.
