Bleah, Its all happy.
The melody that comes in, then turns into a whistling sound, makes it all too happy. It certainly is not epic. IT gives off a different feeling. Next time, add a better bass, maybe some drum elements to it, and build-ups.
Other than giving off the wrong mood, its pretty good and the synths work well together. Just change the title.
Good job this one.
PS Review my latest song please? Thank you.
