That's one dainty glass palace, JBTaylor !
The first, the third and the last stand out -as other members also mentioned- but I also like the other photos where different species of plants and the structure are in the same frame; a little busy but still nice.
All that said, I believe symmetry principles in the first photo are very successful, both regarding the garden and the structure.
Thanks for sharing. Appears you been busy in interesting places again.
Good for you, good for us !
