Ive also been exploring with portrait and lanscape shots depending in what is included within the photograph. See here for example i wanted to include the door and less of the floor and table, i wanted the viewer to understand where they are within the house, yet i do feel that the landscape image also reflects this as by replacing the door by the doormat the viewer can still get an image of where the photo was taken without being so direct.  Im not sure which of these photos i like best as i like them both equally but in different ways.
