Hugo Award Recommendations Needed! Inquire Within…

I’ve never voted for the Hugos before, which means this year is a huge “first.”  Regardless, I’ve always had a problem filling out some of the categories, sometimes because I’m not familiar with the field (comics, for example).  This is where you all come in.  Below is the list of all the categories in which my nominations are either entirely absent or not firm.  What would you recommend I check out to help me fill the gaps?

Best Novella
Best Novelette
Best Related Work (I’ve got four ideas, but maybe I missed something you all know about?)
Best Graphic Story
Best Dramatic Presentation (minus Game of Thrones, as I’ve already seen it)
Best Fan Artist
Best Fanzine (I have ideas, but only one standout thus far)
Best Fancast (ditto)

Have at it!
