Cool shooting day you've had!
Maybe you could challenge yourself even more by picking a very small space, like one park or even garden or one street in your home town/city, and take all 36 shots there. And then pick the 10 shots from that one place that are most diverse/different from one another :-)
In the above 10 shots I see 4 shots with vertical lines reflected in some form of water. They could form a 'sub selection'/mini-series of shots that belong together :-)
Two random comments from someone who loves to look at and think about pictures a bit too much :-)
Hey thanks!
Usually when I go outside to shoot I have an idea where I'll go, like a park, a lake, a street, especially for this challenge. The area above turned out to be pretty huge :D - I must have walked 8 kilometers to go around the lake, the park and end up on the bridge.
I could have made the entire shoot about reflections in the flooded waters. That's a great point! I might come back to do it in one of the future days, if I don't find inspiration elsewhere.
Thanks for the great suggestions. :)
