My two cents: it would be more effective/attractive on its own without the stand. I have several pieces of beach driftwood that I’ve found. One or two might become stands for mame trees, but I have two with natural ‘pockets’ in them. One will definitely hold an accent plant, and the other could make a kusamono/moss planting.
I‘m in the process of looking for a branch end with three ‘legs’ that can be cut and leveled to make a small stand.
I really do like the way you finished the piece to bring out the depth of the grain and the contours.
