I like your drum beats. If this the music was for while you are playing, I think the moans sound effects should not be included in the music, as it might confuse the player with summoning minions or whatever the moans would be used for. But I am imagining an intro cinematic for the first 30 seconds with the title appearing when the synthesizer kicks in, and possibly different music when playing the game.
For the SFX, I think they are too long, when triggering a SFX, I want one good one. Possibly consider layering some together for one more complex sound?
