nice shots, and what an amazing picture quality from the iPhone there! First it seemed to me that most images, maybe except for #7 which shows some amount of sun-flare caused by the remaining obvious physical limitations of such a tiny camera), were indeed taken by a much more "sophisticated" or at least a good point-and-shoot camera...
Anyway, what matters are the shots you captured and the image composition which I like! All the better that you were even "traveling" (or rather walking) light there :)
