That is a very beautiful peace.

*IF* you are Catholic, I can see a very nice orchid/religious ensemble in that wood.
Mount the cattleyas on the outside edge of the wood, start from the bottom.
Then carve the interior a little bit to make room for a religious figure/statue.
After a couple of years, you now have a religious grotto surrounded by blooming cattleyas.
It could apply to other religions as well, if they use any religious representations.

Or perhaps a commemorative plaque for a dear relative instead of a religious figure.

The shape of the driftwood really causes the viewer to think that something significant needs to be in the core of that wood.
