Creature head sculpts

These are a set of creature heads I sculpted in Zbrush last week. I ran a kind of Character/Creature Jam at work, based on the theme of the five senses, as something cool to do before we all left for Xmas.
I avoided reference and tried to rely on channeling any elements I could remember from nature, such as insects and sharks, plus any cool monster heads I'd seen over the years.
I sculpted each of these from a simple polysphere using Dynamesh.
I hope to continue doing these as Lunch Crunch projects in the future.
