The zombie dragon picture shows no bottom picture of the legs. It must be like your picture, only its wings cover its messy legs.
Though I could be wrong. The colors of the zombie dragon on the inside, too, might be hiding it, too.
So I'm not sure, but maybe, just maybe, you can make a tiny bit less transparency to fix it.
Or not, truly. There is a difference of colors in both pictures.
I have been wondering this myself, and apparently made an awkward ghost preset.
Hope this helped~
EDIT: Also, I am not sure about the wings, sadly... Awkward, huh?
