Abstract in Bark

G brought me this curved section of bark a couple of years ago, thinking I might be able to use it for a blip.  It came in handy for this week's challenge of Bark.  Certainly not the best photo of it.  I'd like to try focus stacking to get the curved edges more in focus...one of these days.  The colours and intricate patterns are amazing and I'd like to take a better photo on a more suitable background to show them.
