For three hours this is not bad! Big fan.

Do you still use logic? cus you've defo mastered it. I still consider myself a learner.

Hey great track. I'm a little unsure about the heavy bass that comes in half way through. But other than that a great use of ducking and a nice chord pattern.

Hey, it's a nice idea. Not sure the chord pattern quite sits with me (seems to change key a lot). If you want some advise i'll do my best:

The kick is perhaps a little overpowering in places, drop it down a bit in between build ups for greater effect. Try out some new snare sounds, fiddle around with the drive and frequency until you find a nice punchy sound that fills in the gaps. If that fails it never hurts to throw on an underlying white noise track, this also helps link sections together (playing around with the resonance). Like I said the chord pattern isn't particularly memorable, because it has no key foundation. So find a key and stick to it. There's no rule to say you can't change key to say a relative minor (or major depending on what your mood is) but if you find a chord pattern within a single key you will find it much easier to write tunes and lead parts over the top, which coincidentally you don't have in this.

Ok sorry if I sound a little up myself, but you asked how to improve, and thats what I would do.

Good luck - Duk
