It's called Giant's Teeth and it follows a caveboy who is having trouble being what his tribe wants him to be. It will update every Tuesday and Thursday. You can see it at http://www.GiantsTeeth.com or see the Facebook page at http://www.facebook.com/GiantsTeeth.
After awhile of wanting to rip this site's throat out, I think I've finally figured out my way around. They didn't make it easy. >_< But woohoo! Artwork sharing.
