Good to see you have been active despite your ill health.
If I may be so bold - What I like in the first is the low angle and the 3 deck chairs nicely positioned. They look so inviting, but the people are choosing to sit on the grass. That makes a nice contrast.
I like the second too. The blur and the roots makes it look slightly eerie. The third reminds me of 'Children of the Stones'. A British sci-fi tv series about Avebury and some ancient aliens. It was made in the 1970's. It scared the wotsit out of me and I was terrified of standing stones for years. I think Joss Ackland was in it. Didn't have his funky back pack then
