This is my rendition of the Cave Troll from Lord of the Rings. I used Blender to do the initial modeling, and then used Pixologic's Zbrush to do the sculpting and texturing. The final scene is rendered in Cycles Render. The render was 1,000 samples, 2 layers, and took about 5 hours.

The total sculpt took about 4 hours, with texturing. Setting up to be rendered and modeling the background took additional time. This model is also fully rigged and animated. I worked on this for a period of about 4 weeks.
