I would love some more behaviour and interaction from Fen.
He is kinda like a robot.
Would love some talking, lurking around, teleporting from shadow to shadow, some roars, snickers, idle animations, saliva running down his mouth, some teeth licking when almost in range and some post-vore comments and or animations like picking his teeth, bumping his belly, loud, head lifting burps, snickers and even lying down somewhere for an post-vore nap.
To make him more memorable, more personal, more dangerous and frightening.
Maybe someone here who would love and like to help you! (Just a thought).
Or in short: Please make him more alive
