Getting time for some catch-up comments:
Broken - It has definitely seen better days, suits the mono conversion.
Full - That's handy to have an internal ND filter as an option, worked well to show the movement,
Patterns - That's about the only thing I can grow as they need virtually no maintenance. Interesting change in tone from the centre out.
Tunnel - An interesting backstory, I'm sure the H&S wasn't as strict back then either so likely a very dangerous place to work.
Spring - Nice pleasing tones with the chosen DOF complementing the flowers.
