Thanks to all for the comments so far. Where am I taking it next? I have a few designs, but I need the right piece of wood. Half of the visual result in this piece here comes from the curling in the grain, and at the moment I haven't got any more of this curly maple in the right dimensions.
Looking at the pictures I can see why I had all the comments about the finish and fit of the dot. To be honest, I struggled with the picture for this vase. What you see here is a version where the white balance was adjusted, but it has done a few other things as well.
I can assure you the red dot is about as polished as a small piece of purple heart can be, and this is a plug fit, i.e. there is no glue involved here. I appreciate what it looks like, but I'd be happy to show the piece to Pete on Friday, since we are going to be at the same show, and then maybe we can have a discussion on how it could be improved further.
