To crop... then how much?

This is the question I always ask myself as I am finishing a new piece. It's the question I am asking myself today with this piece too. I know when I begin that I always design the piece to be larger than what I imagine the finished size will be. I don't add to much to the original, but I do allow for what will be under a binding or turned back when faced. I've decided that I will face this piece which. Finishing with a facing seems to have become my preferred method of taking care of the edges of my work over the last year or so. This piece was dye painted, quilted to contour and to suggest dimension. Highlights shading and additional shaping was achieved with fabric markers. I like the fact that I can take a digital image of my work and upload it into the computer and crop and re crop and ponder before I take a straight edge and rotary cutter to the piece.
But today I am really having more than a few doubting moments about this piece. Here are a few cropped images of the piece.
I am going to go hang the piece on the design wall and take strips of white paper and pin them in place and take the rest of today to decide what will be cropped off and end up in the trash can.
Do you have a favorite cropped image?
