As I've said somewhere in the Prom section, the lighting is terrible in that reveal scene. The creature isn't exactly great either, but the lighting just kills the scene. Should have been shrouded in darkness and shadows, if they were adamant in keeping this ending in the film.
It's similar to the mural inside the head chamber. Imo nothing beats the newborn from Alien Res, not even the worst creature moments in this one. Not even close...
Don't think about it when you get to watch the film...
