I was going to attempt to fix this up, but I think it's too flawed. I started again with more consideration into contrast, (my weak point), and composition. Though these are probably still pretty crumby anyway.
I think my favourite is the one in perspective. I feel that I could definitely push them all further, but I have no idea how to.
Any help is greatly appreciated. I'll try to get back into the groove of CA and help with critiquing others, too.
(I always feel bad posting here, 'cause I'm really not sure what's acceptable. I kind of wanted to have input the whole way through this picture, so you all could guide me in the right direction. If that's not cool, just say.)
