I don't find this a very interesting picture, but having been alerted by earlier posts I inspected the fine structures of the wood, and came away impressed.
There's a blue cast overall which looks odd to me, but I suppose is deliberate? Regardless, you've done a nice job bringing out the detail in the wood, it's actually quite startling the way you've pushed contrast into the right zones to bring out all the structure at all levels. Technically very very nice.
