Man, I like these square photos. Most photos have either portrait or landscape dimensions (as far as I'm aware; I won't claim to be any kind of a photography connoisseur), but these have neither, which is refreshing. They're also very nice, imo. This is probably my favourite, because it looks a little unreal and has nice colouring (that diagonal streak, too), but I also really like 'Lovers' and 'Sync'.
Yes, I like the red effect in it! I think if you took it out it might not jump out as much, plus the fact you put the sin in the title and the red color = the sins of the city. I know, lol, that probably doesn't make any sense. I would leave it in
