Sounds like it's too empty
Well to start off the clash that you use for a snare doesn't really fit in the atmosphere you're trying to create with this song.
The vocals are used good, they fit well and they're not repetitive, good job!
Bass is good, could've been abit louder, just a small bit. But your main problem is the lack of variation I think, which makes your bass sound abit dull in the end, try experimenting with cutoff frequencies to alternate your bass sound.
I'm missing some pads, like the one you used at the start aswell as some random sounds that would just fill up the song abit, and give a finishing touch.
Overall it's a good song with potential, you got some work though :)
Also, I noticed a big influence of Omen - Rise (N-Type remix) , if you don't know it, check it out i'm sure you'll like it ;-)
