great sunsets Nick,
a well deserved break I'm sure after all the exams
My pick would be #2, it has the nicest reflections, for me. #3 is nice but it has a bit too much dark sky in the top but that may be different in the original, so I would crop the top a bit.
I'm aware of the dust bunnies.
I just thought they were distant birds
Very peaceful, all of them,
Cheers,
André
