Epic?
A few things, I'll try to make this short. :P
The beginning is excellent, no complaints there. The violin is very subtle, just barely audible and that's actually very nice, it let you crescendo the rest of the piece which I think was probably one of the strongest build ups to this song. The tempo slowing down and then speeding up at 2:04 is nice, however the drums weren't to my taste at that part. They didn't necessarily take away from the part, but I think a lot more could have been done with them, especially when that synth came in. I think it would have helped with building a strong closure because from 3:13 on the energy is basically the same from as the beginning, it's strong but definitely open to be stronger, as that key change shows. At the key change it seems to gather more energy and you can definitely tell the ending is coming. Really, that's all I've got, good job overall.
