It's a gorgeous piece of wood that's for sure and the understated display highlights the focus, which is the grain.
Though I agree with Lorien, that an Egg shape, if done well would not only show off the incredible grain, but would add the extra focus of the crafting of the shape.
It would give the work another level of interest.
That said, I can see that the limitations of the material size informed this design as did the desire to preserve as much of the wood as possible.
Nice cans STeven.
