Go for it Nigel, I'm trying to do the same thing but had set myself the target of posting some new images.
Never been into Tri-X myself or used HC-110 on any film, but I do like the look of these images, the grain looks nice and smooth.
The order of your descriptions of the images, made me think the first was at the Tate until I scrolled a bit further and realised they were the other way around.
Both are lovely images. I can't help wonder what the picture on the wall is, but the charm for me here is the air of mystery. I am not sure that if it was crystal clear and full frame, I would stand any chance identifying the image anyway.
Informal portraits has always been my favourite subject of mine and I really like this image.
