Kinuko, one of the artists behind Scott Pilgrim vs the World: The Game, created all the NPCs in the game. She shared some of the sprites on her Tumblr, so I thought I’d share the link. Note that this entry is fine, but her Tumblr in general is NOT safe for work.

Kinuko also draws as part of Mecha Fetus (note that the Mecha Fetus Visublog is very, incredibly not safe for work). They created the Nice Girls Nice Hats art book that I purchased at Anime Expo a few years ago – 2009 maybe. Anyways, they’re all very talented artists!
