Well you could show what happens after the monster swallows her, she could explore the insides and try to find a way to escape and avoid being digested like an adventure. It could end one of two ways, whichever you decide, she could either find a way out or not... if not, then you could show a picture of her trapped in a room(which is actually the stomache) full of digestive acid, or on its way to filling up. That is if this is not too dark for you.
I can show you a picture of something similar if it could help:
The mouth and teeth emerging from the shadows are so much more scary in themselves! Less is more in this case! The mind will make the monster much more fearsome than the actual one from the Wonder Woman cover that inpired the pic!
I thought you would like the curled tongue...interesting If I do another I am thinking about this one [link] but the one you mentioned sounds good too, I even have magic using villainess to fill the role! Thank you
It's not that I don't like the idea of a slobbering tongue on her (wait, did I just say that? ) it's just placement or more to the point degree of blockage of her body. But hey, this is a insignificant point on a great picture and I didn't mean to make it sound notable. I never met a peril I didn't like.
