Blue and yellow skull thingie

This is mostly cobalt tube, a donut behind the bowl with a spike going through the center. this is the first skull I've sculpted out of glass (can't seem to get very good pics of the detail)....came about from a guy asking me to make him a piece...very vague... he says blue and yellow sherlock style with a skull and a jar.....this is what came out of his request........my skulls now (in 2007) have evolved so please check them out (and ignore this one :)!
