Fantastic! The colors and grain patterns work really well together. The proportions of height to width, and the finial to the body and lid look good.
The main thing I would suggest is to experiment with different shapes, the form is OK, with the top being really nice, but the strait sides could be jazzed up by some nice flowing curves.
Another thing to experiment with is the stone ring. Try different widths and maybe doubling up on some thin rings.
