Did you achieve the overall effect you wanted?
Do you not have any method of finishing off the base?
It is very difficult to determine looking at the images but I don't see an overall enhancement of the woods (Ash?) natural grain patterns.
I see more of a highlighting of tooling and sanding marks I'm afraid unless you have a series of shallow beads texturing the basic curve that is giving me that false impression.
Re-colouring, something I'm not very good at myself but you may find that with an open grained wood such as used in this piece applying a light coat of colour and then cutting back the surface with a fine abrasive will highlight the the grain boundaries more and enhance the grain pattern rather than show just differing absorption patterns.
