Stephen, I think that is a really cool piece, I like it very much!
I do have a couple of comments.....
I added some arrows and numbers to your picture:
Your finale is nice, but I really think that top part, #1 looks unfinished
The part I labeled #2 is spot on, very nice shape and curve, way better than mine turn out
#3 may very well just be the picture, but it sort of looks like a bump or ridge at that point, not a smooth transition from the top curve to the bottom curve
Like I said, it could just be the way the light is bouncing off the black surface.
All in all, that is a very nice piece, keep them coming, and keep experimenting with the dye, I think that is such a cool way to add to pieces that the wood is kind of muted.
Thanks for sharing, and I hope my comments have helped.
Cheers!
