Puzzle ....

My 9 photo's above are the source from which I have to select 5 as a set to be used for a contest at the Dutch Photographers Union called "Series of 5 with Coherence".
Then the selected 5 have to be put in an order that makes sense as a total.
Common subject, common style, etc. But also individually these must be of high quality.
Currently I am puzzling and moving small prints across the table to find the best selection and order ... but cannot decide yet. (see set of combinations ?)
Might become a few sleepless nights until Tuesday.
