@jonthefox One and a half tile high doors look fine, imo. If you look in my edits thread here I did some for people. For paths, the only way is to make them blobby in some fashion. It's tricky with the default path tile, and although I have several that are more rounded, they are all recoloured and on non-default grass so they would be no good to you. However, even if you broke them up a bit, or put in an extra path tile where you have a right angle at the moment to suggest that people cut corners (they mostly do on paths) that would help.
