This makes me think of a Queen Bee in a hive; with the much larger abdominal cavity and reduced movement. I think there's something a bit more feminine about this one, but it might just be me projecting onto it.
is there the same monster? Don't remember. Well, I think creatures from Silent hill inspired me a lot. I mean I didn't have a purpose draw something looks like them, but you know, what you've seen once can inspired you for a rest of life, even if you don't think about it.
