I'm not a big fan of the toning (personal pref, although it might grow on me), but the lines are pretty killer at the alignment from corners to oblivion, with both sides of beach, footprints and waves going to the same vanishing point.
+1 @ retaining the vanishing point provided by the footprints/beach. Also, the one bird right of the footprints interrupts the path from the corner to oblivion. So since it's on the road to oblivion ... send him there express, via the clone brush. Maybe the low flying bird/reflection on the left as well.
