As someone who is fairly familiar with Silent Hill games, I've got to say you really nailed the colour scheme on the Pyramid Head Ogre. The conversion is pretty great all around, excellent work. I've been looking into Silent Hill myself for inspiration regarding Chaos (especially Slaanesh) recently and I've actually got my own Pyramid Head -inspired Chaos Champion in the works (still in the planning phase, though), so it's nice to see that it can be pulled off, like you have.
Great plog all around: excellent colours, some good old minis and nice conversions. I'll be following this closely. Erinomaista
