I think I got carried away with my brush icon. Was too fun to stop, and it went fast anyway. Can't wait to use some of these on my current sculpt project.
Using PureRef, these are my most used photos for inspiration. From just a few resources, you can make a massive variation of details. That horned toad alone has a dozen more amazing scale "types" that I didn't do (yet).
I watched one of the many Drust videos. This is obviously the one on creating a VDM brush. I got into it. Represented here are the brushes I made over the past 3 days after work. I combined them all into one multi alpha brush. I'll share it once I feel like it's done, but it's far along enough for me to start using it.
