Brush texture and invisible cities

Since I got a good response for my life drawing sketch from Phil (Hi Phil :) )

I wanted to incorporate it with my project. So after a quick chat with Jordan today, I made the drawing into a brush for photoshop.

I love the texture it creates, at first glance it looks like a really good start for rocky surfaces and possibly with some additional editing, clouds/steam. I did a quick concept thumb for Octavia using only my mouse (what a rebel!), so ALL feedback is welcome.
