I love it

Interesting song. It's the percussion that you don't expect. It gives the song a bit of a more marching quality or dancing (more oomph). Very spooky as well. The wolf howl and the low pitched laughing effect also contribute very well.

Yeah, nice, reminds some gothic SNES games)
and the part two is good, especially arp 1:05, this is so castlevanish, you know

Nice job, truly spooky.
I'll recommend to use more instruments to "fill more the void" like a choir or some strings.

Nice atmosphere, the melody and harpsichord remind me of old SNES video games and Professor Layton games.
Have you considered EQing the howl and deep laugh so that they sound further away? I personally hear them a little too close to be atmospheric, and would have cut the treble on the laugh and the bass on the howl.
