I fell in love with Jana's painting of marbles for this challenge(http://janabouc.wordpress.com/) and wanted to give these orbs a try. With small grandchildren visiting frequently, though, we can't keep such things around for fear of them being swallowed, so I resorted to a reference photo for this sketch. Getting a shine and reflection was so much more difficult than it seemed! As well as getting a close circle!!
A fun challenge -- heightened by Jana's raising of the bar!
