First Off, great mod. Absolutely amazing for custom work. I can tell it's a work in progress mod, but it's shaping up to be something great. I've played the games from start to finish, so if need be I can give a few tidbits of advice for you. These include:

-The Closer's walk animation has its arm sway side to side, forward and back

-Insane Cancer has an attack in which it slams down on you with its arms with the girth of ten sumo wrestlers

-The walking animation for the slurper has its arms moving as well

-Scarlet's double handed swipe attack is...strange. In the game, her waist literally spins 360 degrees as she swipes at you

-In Scarlet's first phase, she has a slam attack

The rest I know you can fix over time. If you want to add more Silent Hill enemies that are not on the workshop, then I do know where you can get others. Just go to DeviantArt.com and get the files for the models to port onto here. Then you can have your way with them. Best of luck and good wishes on your behalf.
