I love the MLK poster, which quickly explains what this marade (marching parade) is about. I think the shot captures Colfax pretty well, and Denver too. The girl in the gold jacket serves as a nice foreground center piece. The name of the cross street adds a nice touch too (but I can only wish that were on purpose).
I barely edited this one, believe it or not. I love Francis Bacon's self portrait, which seems to be watching these two museum-goers. Love the balance in this picture, and the colors too.
