Types of fanworks you can beta: Anything with words - I can cheerlead non-word items, but not give critique.
Things you can beta on the fanworks: I beta it all - grammar/spelling, plot, pacing, structure, character voices, internal logic, whatever. Unfortunately I am not good at limiting myself, so if you only want a few of these items, I'm probably not your gal.
Comics, movie, or both: Movie only, sorry. I will read the comics eventually, I'm just... putting it off. /o\
Type of beta you are: Sea of red. I write about 1 for 1 with your wordcount and am very wordy. I try to be very thorough in my explanations as I don't generally want authors to feel bad about their babies but I do want to polish the stories/poems/meta into the best story/poem/meta it can be.
Anything else you'd like to add: I will probably not have the time to manage massive fanworks this season, unfortunately. Anything under 5k is fine; once we hit above that, I'm a little hit or miss, due to my tough work schedule.

I have no squicks or triggers and will beta any rating, any pairing, any category.
