working with the ZBrush Advanced brushes

These are a few concepts I did to test the new set of Advanced brushes for rock creation in ZBrush. A bit of everything for the final composition. Keyshot renders, photoshop paint-over and a bit of photobashing for texture.

The set of 50 custom brushes is available here:

Hope you guys find it useful!
