I like the melody, you have progression down okay but one quick tip to make your sounds more full is to layer them using the same synth. Make 2 additional copy's of that synth 1 octive above and below your main. or you can look up and study chords and use that in your main note sequencer instead of using option one. what ever suits your fancy or is easier or sounds better to you.

Ahhh ok thanks for the tip; definitely increases the 'epic' factor; ill apply this to future songs.
