Nice shot of Mt. Rushmore:-) I love the leading lines with the pathway of flags that leads the eye right up to the main subject. While a good shot there are some things that could be done to move it into a above average shot. This scene has a lot of potential. First, I noticed the angle of the flags would match rather nicely with the downward triangular slope of the loose rocks. Shot at a lower angle looking up those flags could then act at the pointed up "V" shape that outlines that loose rock slope & the bottom half of the composition *AND* act as a leading line/up arrow that subtley points up at the presidential monument. Shooting from a lower angle and better use of the leading lines presentation to complement the scene would also take focus off the bland white featureless sky. Lastly, I think that the shot could do with just a touch more contrast (bump it up a little in PS) to define the areas of light and dark on the monument itself; not too much just a little more to make it pop a little more such that it does not appear too washed out compared to the bottom half of the composition.
It looks like the first guy's got a big dollop of bird droppings on his head.
Oh, maybe it's just a bit of sunlight. ;-Þ
Actually, quite a good fit for the Challenge,
