Ecto cat

Welp, I'm working on a super weird thing called "Ecto cat's" anyways, this is how an ecto cat looks,

They can have any outline color, but the glow must be a lighter version of it.
They have to have a ghosty? I guess, back; but they keep the front legs
Wings are pretty improtant. All Ecto cat's must have wings; the ones with bird/angel wings died peacefully, forgiving, or just accepting, etc. Cats with bat/demon wings died unfairly, angry, cold hearted, etc.
For "dark?" ecto cats, they have have the same things as a "light" ecto cat, but, they have bat wings and where the blank/white part of the body are, it's all a really, really dark grey, only a little lighter than black.

Also, the mouth is usually like an X the top part being the nosey and the bottom the mouth ^^
