The shadows are a killer on this one. If the emphasis wasn't so much on the repetition end, it would've been a little better. I think this just would've been a better picture if the pillars were all one solid color.
Beautiful perspective shot. Love the afternoon light, but IMO, the shadows are little bit too busy and distract from the beauty of the columns (others may like it). Slightly different time of the day (perharps few hours earlier) would have helped with more light.
