You have managed to ape the three basic categories of gore, sexual tension, and controversially religious imagery that define Silent Hill, unfortunately you’ve sort of missed the entire point, which was that every Monster in Silent hill had a point. They weren’t just tits and knives stapled together and covered in blood, they were organic, shifting representation’s of the SUB-CONSCIOUS. And–oddly enough–there was rarely(if any) actual frontal nudity or direct affrontery, everything was just hinted and whispered about, circumspect.
Your model is much closer to grindhouse titillation than it is to actual psychological horror; you might want to rethink why you made it the way you did and what you hoped to achieve by it.
In re: The execution of it:
It’s way too clean for something that’s supposed to be a grisly monster. There’s no blood, no dirt, no rust. It doesn’t look like one whole thing, either. It looks like the corpse, the rope, the cross, etc. are all just sort of positioned NEAR each other in 3d space. There’s no obvious degeneration anywhere, the monster seems totally clear-cut and upright. It’s not really scary at all.
So what you could try and do is try and arch the body a little more, twist it, buckle it a bit. Work some agony into the pose, and crush all the contact points on the mesh closer together, so it looks like the rope is really digging in, and the body is really pressed against the wood. Then stain all the textures, add rips and smudges, and blood around the amputations, and put rot and dirt in all the crevices, so it looks like the thing’s been stuck together for ages.
That’s what you COULD do, but personally I’d work on your design first, before trying to model any more of it.
