OP, I used to play guitar, hung it up two years ago because life got in the way unfortunately. The only critique I have (and don't take this as detrimental to yourself or your skill) is that you should get a backing track (or MAKE one) and play over it. I say this because the first half of what you are playing doesn't seem to have much context with regards to halo, but the last half definately does. I didn't recognise anything Halo'ish from the first minute. Play over a backing track and I reckon that the start (the first minute) will "come alive" more. Seriously, please don't take this as a flame in any way whatsoever, but advice. I hope you re-do this with backing. GJ nonetheless. Jim.
