Heya! shutterspeed is a community for challenge-based photography, usually with two challenges at a time, but we're in an amnesty period right now, when photos can be posted for any of the previous challenges (you can see the list of previous challenges here).

I think your first two pictures would work for our previous "water" challenge, and your third picture for lines and patterns, so I'm going to tag the post to reflect that and make you an author tag.
