I really enjoy this song because of the effect I've used on the guitar, it seems that I have a synth with choir, but in fact not!
The reverb effect makes the guitar sounds like it's all around, the palm muting is indeed too much used and the song is too much repetitive too much repetitive too much repetitive...
The melody is inspired by the Bermuda Syndrome game (an old platform pc game taking place in an island inside the Bermuda triangle, our hero is an aviator and he must fight dinosaurs and many traps in order to save a princess and her kingdom etc etc) and the OST from this game is totally amazing.

The last section of the song makes me think about the Baldur's gate 2 theme, I don't know why.

Hope you enjoy it.
