"Klingon skull" - the back blew out in bisque... I figured I'd roll with it. Unfortunately it has a stress crack on the bottom from making the drain hole so I'll be keeping this one, along with the big rectangle.
Thanks. I really like the "ancient rustic" effect right now. Next is to build up a glazing process that enhances it all. Shame I have those stress cracks on the rectangle. Not a big deal structurally so I'll just use it for one of my trees.
