Is that a wingged hermine ?

What do you mean by hermine?

It's a french word for an animal looking like this one, but without wings, all white.

Oh, so you're talking about an ermine! I took the weasel as a basis, but weasels and stoats are very similar to each other. In any case, my animal is not a winged weasel, it is a little different.

What is it then ? Tell me more. O W O

This adopt has longer and hand-like front paws, much larger claws and a longer neck. The hind legs are better adapted for hunting on the fly, because of the slightly elongated shape and the same claws.

In this version https://www.furaffinity.net/view/43144764/ I also changed the tail, added small webs between the fingers and horns :)

The changes are not particularly significant, and I think that the future owner will have the right to do what he wants, including making the adopt just a winged weasel. But I conceived these animals exactly like this :)

Mmm, very interresting. You have some good ideas, I always like to know the creation process.

Still I've a huge pref for this critter, that's stupid but the others just look more "ferals", less friendly. I enjoy my noodle friends with cute and gntle faces, like a kid. xD

This is not stupid! These creatures were conceived with different moods, I'm glad that their character can be traced ^^
I like your choice :)
