Your larger scans are much better. They do show interesting seeing.
Since you are not yet processing your film, I'd recommend getting books of photos and really studying. Look at what makes the pictures work. Get anything by Michael A. Smith, if you can find his books. Or go to his web site
I'd recommend going to the library - look for Edward Weston, Atget, Ansel Adams. They don't photograph the kinds of things that you do, but they are masters. Studying them will help your vision and give you a sense of the history of photography.
Keep reading this forum and asking questions. Good luck.
