It certainly has a nice tension for an intro. Sort of as if it was going to pull me into a sci-fi fantasy space game.
Timpani and cymbals are needed to make an epic intro! imo.
look... this is not epic, but i will not judge your music from your tittle. this is a good song. but it's missing something, try to put more instruments on the "background".
Well, thats it. continue in that way.
