Sometimes, it seems all I remember of Milan is its gothic cathedral. It is thorny and yet graceful, chaotic and yet impeccably ordered. For this shot, I deliberately left out much of the facade, choosing only a small area to focus on. For those who are interested, one useful composition rule is the Golden Triangle rule, which I employed here. This rule has its roots from the Golden ratio, which harks back to the days of Pythagoras and Euclid. For an easy-to-understand explanation of this rule, click here.
