Unless I'm mistaken you have a bit of gap between octaves in the first half minute or so. It's mostly just the highs and lows. Maybe flesh that out a little more?
1:12 I'm not sure that that little pizz glissando thing is actually realistic (or even possible) for an actual performer.
1:15 - 1:30 This part felt a little bit formless.
1:30 - 2:03 I'm going to be honest. I wasn't really feeling this part. It didn't seem like it fit in with the rest. It felt a bit too silly for my taste. Then it just ends and is completely gone thereafter, which feels quite strange.
2:37 The chord you use right here is interesting. Try and use more chords like it. Spice things up more, you know?
Also, dynamics. Use them more.
Overall, my biggest criticism would be the lack of uniformity. The whole thing just felt like it was drifting from one theme to another and not really developing each as much as they deserve to be. Try picking just one single theme and stretching that to it's fullest potential. You might be surprised by how much music you can get out of one little idea.

That's probably not a good sign. All the best musicians I know spend far, far more than a few hours on a single song, no matter what the genre. It's better to have a few really golden songs than a million so-so ones.
