I really like your Frisk. I think it can be too easy for people to turn Frisk into too much of a 'goody two shoes' with no personality beyond being 'nice', but you do a good job of keeping them human with an optimistic core. I always get a sense of consistent personality in your tags and I enjoy both reading them and tagging with you. I've seen Phi less, and I'm canonblind to boot, but she feels very distinct from Frisk.
