Useful critiques are hard enough in person let alone in a virtual space where there is no eye contact and no "real" object to discuss. To be honest, I'm not even sure there is any real value in having any work critiqued unless you want evaluated on technique and are clear about the level of application of said technique you were hoping to achieve - but that is just skill building and sculpture can be so much more than that!
Love the links Rika. All figurative - of course
Personally I've been making sculpture for about 20 years now and I have yet to throw a pot. I was just never compelled by the material or the (seemingly) required love and knowledge of the science behind the craft.
