I like the origin.(except frog size. Because I want Players to be normal sized or the size of a giant mob, iron golem, warden, elder guardian, wither, ender dragon, enderman or wither skeleton)

But it's useful for these skins(especially Rana, Kermit the Frog, or someone who is wearing a frog onesie):
