Piano, the progression of it is pretty bad.
That bass in the background is too loud is kind of drowns out the piano.
This doesn't really sound like ToE at all, all this is is a dubstep song with a piano.
The drums need better sidechaining.
You need more percussion
The sound design of the dubstep sounds are pretty bad, and so is their placement. This song is also a bit too repetitive. Theres nothing too exciting about it.
The mixing could be improved too.
Also try adding background sounds in there, I only heard a piano, drums, and dubstep sounds...
Overall 2/5. Sorry if I seem harsh, I'm just trying to be honest with you mate. This song is a good example of how overrated dubstep is on Newgrounds.
