To be perfectly honest, I think Siypha is the character I have who's changed the most. She started as a name for my Pokemon Reborn playthrough, then became a jackal, then Green Lantern (which she still kinda is), and now has settled as a semi-aquatic rabbit-crocodile-dog mix. Quite the evolution!
She's the second character I've made a costume of, after Noroi. It was something of a test of fursuiting techniques, but in a fabric I was more familiar with, stretch velvet. The mask turned out especially well, I think. It started as a papercraft Anubis mask, since I wanted something that fit close to my head, rather than a more standard fursuit head style. While pup masks do fit closely, they don't have long enough muzzles. It took a bit of playing with the scale, but it fits really well, and is secure even without a chin strap!
Anyway, on to the doll.
