Every couple of days, i'll dig into my pile of old sketches and post one that i'm still kinda happy with.
This one is a gaur, basically a really bad-ass cow.
Oh, and a mammoth too.
You can find all of my assorted doodles in my Conceptart.org Sketchbook thread,
which I have been updating more or less regularly since 2005.
There's some pretty scary stuff in there, so please skip the first 60+ pages.
