Don't do that! :s
Repeating the same 16 measure melody for 3 minutes, trance or not, will get old. You have some slight bits of variance through the song, but it's generally just the same thing endlessly with some volumes changing over the course of the song. It's a pirate-like melody, it could eaily be expanded upon and add some variance to the song without hampering the "trance" part of the equation at all.
Aside from that the production is nothing to write home about, but not terribly offensive, so things could be worse, and redundancy aside the brief melody that is there, while a bit of squandered promise, isn't at all bad. You just need more to it, and a little refinement.
