Great..

Interesting modification on a common chord progression, I like that.
This really gives me a weird 'video game'ish mood.
I find the beginning a bit repetitive with the pizzicato strings repeating its rhythm for a bit too long.
The pads seem a bit cheesy too. Perhaps add some effects?
Great song you have there. Really reminds me of runescape. (Don't ask me why, just feels like it.)
