Very surprised to have one, although going by the comments it was very much a vote for the subject matter than any skill behind the lens.
So, to the next theme:
I've just spent half-term visiting various relatives, so "Out of my element" seems to be rather apt.
This could be literal: something outside its natural element, eg something that should be underground being in the air, something that should be in the air being underwater
or figurative: something just in the wrong place or situation for it / you
I hope this theme works out, good luck and enjoy!
