melody has it
Good base melody you have there. It's too bad that the song gets a bit repetitive after 2.05.
This could be a great song if it had a bridge part. What you do around 2.40 is good, with the change of octave. But i'd be even better to use a different melody, or alternate it a bit more, so the song doesn't get so damn repetitive.
The first part (first 2 mins) and outro are great by the way!
