Ha I know the feeling buddy (keep creating and I am sure you will start to get hits). where/how much do you sell them for? If they are in my price range I would love to own one of your beautiful pieces in the future. If not now, within a year I will be making much more money and want to support artists I respect and envy to an extent.
Most of the trees I have sold have been in the smaller range, unfortunately the more time they take the more beautiful and expensive they are. Mainly though I sell hang-able art which again I have dealt with the same issue. Good luck and again, beautiful work; burl use is a great touch and I may have to steal that idea for the future, though I don't think I will ever touch your craftsmanship and time.
