Thank you Lois, your comments were helpful so please do not push off.
I am not a landscape person, but find this site extremely useful. I am tempted by HDR, but am aware that most practitioners misuse it to extremes, so glad to be told that mine is "subtle" but still your comments will encourage me to tone it down some more. Actually, only the street scene was HDR, the others perhaps overused LightZone.
The trees in snow was the most like a snapshot of the four - I just pointed and clicked.
I spent a lot of time composing the door. I liked all the rectangles, the multiple vanishing points, the suggestion of other openings leading off to unseen places, the hints of people living within these rooms who are suggested but not shown, the changes in tone of the same coloured walls.
I prefer cityscapes to landscapes because I like the energy of the city and hoped I had captured that in my street scene.
The kitchen shot was a bit of a joke, but I was trying to capture something real rather than a Homes and Gardens shot - sometimes my kitchen is a mess.
Thank you again for your helpful remarks
