Here's the final render of my art trade with KhramChee.

Originally I tried rendering a larger image with medium-high sampling, but that fur system really kills the processor, would've taken 14 hours to render! Well, that wasn't going to happen, so I dropped the resolution a little and cut back on sampling. I don't think the final image has suffered any for it.

Final render time: 3hrs 19m.
