Nice shot, I would have tended to go towards higher contrast and lower brightness. The cuffs have an almost butterfly shape to them, unsure as to whether this was intentional, but this conjures up memories of "Papillon". A well trained butterfly, at rest, atop the cuffs would have been an assured winner.
I like the color palette and tones in this shot. Along with the metal cuffs, they create a juxtoposition with the theme and butterfly pattern. Great job.
from someone who wears cuffs everyday to work for a living, I find this just so nice and creative! Great idea!!!! Just when I thought I knew cuffs and nothing left to them this shows me a creative side I never thought of. Now I can look at them and see a butterfly =)
