Lower tier architecture gives appearances of "fish-eye lens," except that I am sure it parallels the curvature of the fountain. Great little added surprise to the photo! :)
Waldo is sitting at the edge of the fountain. Good exposure but the whites look sort of yellow to me. That is if this is a white building. If not then disregard but if it is supposed to be white then it could be fixed in pp with levels or possibly by a slight desaturation in the yellow channel.
OK well I found Waldo by the fountain (Is there another just by the second floot hut as well?) . Very nice shot and the centring works well. the sky colouration is fantastic is this through a polarising filter or PP work, either way it gives a remarkable feel to the picture
