the over exposure blends the slab too much into the sky on the first shot. Some careful editing of the contrasts may help with that. Try shooting with a lower Apature next time to blur out the background.

First, I've got to correct you on the spelling, it's spelled Shiloh. Sorry, I have OCD when it comes to that sort of thing.
As for the photos, I am a total noob, but I think they look great. The second one is my favorite. The second photo seems to give the statue an emotional quality. Nicely done...
