It flows pretty well, it sounds foreboding and ominous, and it is a little catchy. However, the percussion is messy and out of place, it sounds good with the rest of the song, though.
You have a catchy but very repetitive song here.
Keep improving ^^
Ugh. Your right. The metal like things at the beginning. I had kinda intended those to be out of place, and I think its a nice chaotic touch, but the main drum beat could be reworked. Thanks for the constructive criticism.
