This statue is probably the most photographed location in central PA! I had my family in town and we were walking around the campus one day and didn't really have much to do, so I said "what the hey, lets go to the nittany lion shrine, thats what people do when they visit campus" and there were 2 other families there already, so there was basically a line, 3 families long, to photograph this lion! we ended up just leaving without walking up to the shrine.
anyway, that being said, I agree with the comments about white balance, something which is totally correctable if you shoot in RAW, but should be payed attention to while shooting if you shoot JPG. Compositionally I like the third one the best. It is a huge statue, and the others don't really give reference to its size. The close angle doesn't exactly give a reference of its size, but does represent the size because it looks bigger in the frame. With such a hugely photographed statue, and frankly one thats not all that exciting when taken alone, the pictures that stand our are extreme points of view and things like that.
I have a hard time capturing sculpture myself. Though I always try if there is a statue, but they usually come out very boring. I'm not really sure why.
hope you enjoyed your time in good ol' state college, as suggested above, I'm currently there
