I don't know why, but i always find monster girls
that are more "realistic" looking ( such as the girls z-ton and oumasu draw)more attractive to me then the usual just put a sexy human girl with animals ears or other parts.
I would say OP's pic is about 1.25 to 1.5.
Is already crossing over 2 though.
I always thought , that Monster Girls with more "Monster" than "girl" are necessary, sure for me ,they are
unattractive, but it really drives point , that they are dangerous, like those girls from MGQ, then they will finish translation?
Pic Unrelated of course
