No bans or bashing me, he sent me a message specifically asking for my opinion.
I'm going to rate them on a percentage scale of how much I like them with 100% being your first image, which I would consider to be the best in the set and a very good image (not great or a show stopper, but better than just good).
1: 100% - it works... it draws me in and every time I look at it I feel like I'm about to start spinning (to my left actually).
2: 80% - I like this one, I think it has nice vertical lines and is framed nicely by the half-man on the right and left and the brick floor on the bottom.
3,4,5: 30% - They just don't do anything for me. I'm not sure why, but they're just sub-mediocre to me.
6: 10% - Bleh, I can't find anything to hold on to here.
7: 60% - I kind of like this one, definitely a keeper and one to throw in an album anyhow.
I can't offer any cropping or angle advice, it's just not something I'm capable of doing without having been there.
