Well, I personally strongly favour the first one - I'm one for any diagonal lines in photos, and I find those both in the ceiling lights as well as the windows, so I just love this one.
"No flash allowed" is a challenge, and one that I sometimes try to take, too, with varying results (often my waste paper basket gets a lot "to eat" then), but those that turn out make me squeal with delight.
So I do appreciate that you took that challenge with the wonderful old equipment you're using, P (does that stand for Peter, maybe?), and must say that you succeeded very well.
