Hey, just listened.
I think it's important that you should be asking yourself what you are going for.
Are you going for a distinctive sound... The drums are very electronic, but the guitar has a more rock quality. The piano is obviously a nice reference to Silent Hill 2, but I think together these elements just don't gel.
In reference to what you probably want a Silent Hill remix to sound like, go for more atmospheric pads, and you can mellow out that piano a bit with the writing, right now it's just a very flat way to carry that melody.
Your guitar is very nice. (the later guitar, the riff that repeats I think has some timing issues)...
I don't really know how else to comment until I hear more, but for now, work on making the piece more cohesive as a whole that = more than the sum of its parts.
Also and I'd probably focus on a more rockish kit to emphasize that guitar, or a more Silent Hill electronic (trip hop, industrial) kit for atmosphere, whichever works for what you're going for.
