Neat subject, great IQ, and apt vertical comp. I'm OK with the vertical part of the perch but I am not a big fan of the amputated limb below, and as such I would crop to just a bove its' end. I would also fill in the white area at upper left corner (the rest of the BG looks very nice). Love the raised leg tucked close to the body.
No, I don't mean to crop along the bottom of the horizonatl perch, but rather at the very top of the round cut-off part (or the very tip of the "triangle" BG part in lower left corner...)
