Does this name fit this creature?

i'm writing a book where every night when the sun goes down, the creatures become serpent-like [eyes turn into slits, eyes turn a shade of jade], they have serpent-like desires [striking, sudden movements, ETC.], all of their movements cut through the air as if they were ice, very strong fighters, tough skin [bullet proof but not as hard as granite or cool]. i was thinking on the Sphyn for the creatures, does that sound like a good name to you?
