beautiful

This was so gorgeous...without the houses in the background at the bottom...that's why I did a horizontal shot and it's bugging me but it looks so much better without the houses in the background...did I do this wrong?

I was in Gubbio (Umbria, Italy) for work last week, and had the time for a short visit to the city. I took these shots:
Piazza dei Consoli
Bike
what are these plants called??
the Roman theatre
and my girlfriend took this, which is the one I like best!
