One big thing I like to suggest is to use
TV Tropes as a resource.
Storytelling in tabletop RPGs in a lot of ways
needs to be cliché. The stories take so long to tell, and it's so easy to miss things that your fellow players or DM say, that if you try to do a lot of subtle storytelling it's very likely to get lost in your players' minds.
Tropes are good because they are patterns of storytelling that people will consciously or subconsciously recognize, and make it easier for them to remember.
