As above - I really love them, especially #1 - looks like a beatifully lit stalagmite.
#3 reminds me of a classic pic from the past - but I don't recall it being this well-composed. Was it something wierd like an advert for milk? I seem to remember reading an account of how it was done then (in days of film) but I can't remember the details. :bonk: Does anybody else remember this?
