I gotta say, I think this one is lacking something. Technically, I'd bump up the contrast. But it's just missing a stronger subject -- shadow patterns in and of themselves don't usually do it for me. Need more more context here.
I think it's an extremely boring subject really. But a very good photograph of it! Think about it, shadows on the ground? *yawns* But with a little knowhow it turns into a good abstract, like here. Well done and thanks for letting my mind wander as I think of way to copy you. :mrgreen:
