The cover artwork for the third of my Fox Meridian books, DeathWeb. A six hour IRay render, but I think it came out pretty well. Lettering added in GIMP.
It's not surprising that it took a while to render, really: there are a lot of light sources in there, all of them mesh lights. Three actual primary light sources. Each of the web strands is an emission source. The trim on the dress is also illuminated and this is the first image I've done with this model where that really stands out.
