First I looked at your pictures and appreciating these are tests I thought they were nice. I liked the composition in pretty much all of them, thought they were generally pretty good pictures and couldn't see what was wrong with them.

Then I read your description and if you hadn't mentioned the skies look added in I wouldn't think twice about it – now I can't stop seeing it. It really does touch on this feeling I've had towards my own photos for some time, thinking something is off but I don't have the expertise to understand what. I think you may have just nailed it for me – thanks!
