Starcrossed

Starcrossed is a story about a closet lesbian high school student named Quinn Morrigan who prefers to ditch school and play guitar rather than the norm. She aspires to be a musician and may or may not have delusions of grandeur. No one knows for sure because she’s always daydreaming. All in all Quinn was just an average high school student who’s just plain bored, that is, until a meteor shower changes her life.

The webcomic contains examples of following tropes:

 * Aliens Speaking English - Seren speaks perfect English upon meeting Quinn in person. Though says their official language is Esperanto.
 * Bumbling Dad - Quinn's Dad
 * Schoolgirl Lesbians - Quinn and Seren
