Folks, which thumbnail do you prefer? Asking so I can polish up one of them (Title explanation in desc)

First one, that one seems more scary has the shape shifting vibe
the second one seems more like a video about mental health

So I'm making a gcmm about a shapeshifter girl from another world suddenly being sent to earth, and having to keep her true form hidden from everyone else. So not only is she in a new school of unfamiliar people and their social norms, she ALSO has to constantly keep up her human disguise facade ongoing no matter what.

(Her true form is pitch black)

The girl however, accidentally shows her true form to a person who promises to keep it a secret, at a price...

Things go sour from there. (Not telling too much yet)

First one. It gives that horror vibe to it.
