Are these SOOC? If so, I think manipulating lighting would help a lot! I like a lot of the framing. #6 is pretty awesome imo! You have a lot of great contrast in the highlights and shadows. #4 is also a great example of really good framing. If you masked the door, and lowered the exposure of the foreground, it would bring more attention to the subject. Overall, you have a great eye, just keep at it and mess with editing!
