I like the light, shadow and the smooth swirl down! B&W is quite fitting too!
Nice picture. I like that it is B & W. Brings out the detail. The only thing I might have done differently is crop out the people on the right and the black thing on the bottom. It is a little distracting. Did you photograph this in B & W or change it in Photoshop? I love B & W and miss my B & W film days.
The shadows just add to the "geometry" of it all.
