Leah is most like me in terms of personality, build and interests. She's just an average, giant, furry, wannabe artist rat, yeah. Socially awkward (genuinely, not in a quirky way jfc), lacking self confidence, loves to be loved and generally pretty submissive.
Frost is kinda a nsfw fursona (but not always, only sometimes), you'll definitely find they're often the victim of my curiosity. They are attached to any nsfw accounts I may or may not have.
She is female, but love love loves to crossdress and prefer to be referred to as she or they - especially when dressed in boys clothing. She's highly fashionable and wears all the clothes I wish I owned/could afford/could look good in.
Jae is my half-sona, or a "fursona with a story". She's not a character that's just 'there' like the other two, but is part of a large universe and story and has many aspects of my personality, some of my looks (including the ears) and my style. She is also the character I wish I could be, both in a realistic way of "wow I wish I was that confident" and fantasy way of "wow I wish I could live in a giant alien city as a shape-shifting thief".
