I'm with Pete on this! I find that cutting back the upper surface of the wing to leave an upward step to the rim of the bowl, helps to define the edge of the bowl, but also gives the illusion that the bowl passes through the board, which adds greatly to the general appeal of the piece. It's advice that I was given on this forum, about 3 or 4 years ago when I made my first bowl-in-a-board, and I find that it works well for me and appeals to a greater number of people. I'd also comment that the wing could have been thinned down somewhat, giving the appearance of lightness; this one looks a little heavy!
Having said all that, there's no detracting from the fact that both of your recent bowls are beautiful pieces of timber that have been well turned.
