www.gameartisans.org has been hosting regular speed sculpting challenges, just for fun.
Today's theme was cowboys and Indians.
Sculpt took about 2 hours, the idea being to just get the basic forms down, rather than produce a flawless, finished bust. Which is why it looks a little shoddy in places.
These two were done for the previous days, when the themes were 'badass' and 'femme fatale'.
Again, not the best sculpts, but quick and fun.
