I like all of the shots, but the processing needs help. First one needs more contrast maybe put some of the shadows back in it, the second one needs less shadows in the bottom, third looks underexposed but probably be corrected in LR and the last one has way too much saturation. For me the composition is good, but your technique for processing needs some improvement. Im not a pro so take this with a grain of salt. But thats my opinion.
I think the photos were done well and they're nice, but I can't help thinking that you've shot yourself in the foot with regards to originality. There are at least four other 'togs there that have just got EXACTLY the same photos.
Let's just hope they got their white balances wrong
I mean that a lot of people were all taking the same photo at the same time. Your photos are very good, but those other people have shot the exact same photo from the same place at the same time.
Maybe you could have found somewhere better than them to get the shot.
