Thanks for your comments. A couple of people preferred the
rectangular crop, but I prefer the square format composition as the
majority did.
I presented it full frame, even showing some of the negative bleed
space, but the finish rendering will take a small trim crop,
maintaining the square, to eliminate that left-edge issue. To my eye,
that's the distracting element in the full frame image. The final
sizing will likely be square 11x11 in a 16x20 frame for sake of wall
space in the gallery, although I'd prefer a 13x13 rendering in a
20x20 or 20x24 frame.
