Good for a creepy song, but it only had the basics
Well, i listened to it.
And expected something more great, amazing.
But the only thing i heard in it were some drums, a main instruments that has one simple melody and a kind of bass.
Hmm, with this i only want to say you, your song could use alot of improvements.
For example, if you want to make this a really satanic song you could add backwards messages in it, you can use your own creativity to come up with evil messages backwards.
And as second thing, you could add a low-pitched voice that is making murmur.
And you could use a high variety of different kind of melody's, like adding strange sounding melody's.
I 'm not sure how to explain what i mean with that but you probably will understand.
Positive things were that the sounds you used, were sounding good for a creepy effect and it could be really good music for a scary movie.
I hope i helped you, good luck for your other songs in the future ;)
