I came across this artist, Carol Hummel, while I was looking at the cozies on The Microwave. She works in many fields: her website shows sculpture as well as prints and photographs, however I find myself most drawn to her sculpture work, especially her recent stuff.

Check out her site- she does a great job explaining each project and provides a lot of pictures for each.
