I voted for "Pug Girl". It's more personal and allows for the viewer to create his/her own story. I think it's difficult with architecture shots to achieve something beyond the generic "holiday snaps" kind of feeling, but the last photo is interesting. Maybe if you cropped the sky more so the horizon is in the upper third and the dark water and reflections can become the dominating focal point? Just an idea, but that would certainly sell the mood for me more and I would have chosen this picture if that were the case.

Hope this helps. Sorry if I sound like an arse. Not my intention.
