I love the idea and the BW conversion. IMO, the incomplete seat on the upper left is distracting,, maybe a tigher crop from the top wool take it over the top.
p.s. I tried scrolling and it changes dramatically. About half and inch.
Agree with Fabs on the points made. Did well with the conversion, played around with the picture in PS and only got a little more out of it with selective color working on neutral/black increasing a little bit !!!
