This is my second sculpt in zbrush. It was based off of this concept art done by Noah Bradley http://i.imgur.com/KdRFvkw.jpg
It was just a project I did for fun and to get better with zbrush and sculpting. I still have a lot to learn in this program.
If you would like to see the timelapse video I included it in my latest "3D Weekly" for my website which can be found here
I'll probably update it eventually I'm just pretty busy at the moment. I want to texture it. I might make it an underwater type scene or something I'm not sure yet.
