I enjoyed this.
Hmm... Where to start. There is alot of raw potential here. You're GREAT, but your talent is raw. But that part you already know.
Very few songs can get away with such a repetitive core for the song. That particular arpeggio, is complex enough to get away with it. You got an incredible song from what seems to be one instrument. It's rare that you have the ability to create a memorable bass line from the same instrument you have for your treble. Very rare. I love the falling in and out feel of that arpeggio you've got here. It creates the illusion of increasing, and decreasing distance from you and the amp. If yer a science guy, think the Doppler effect. On that note, never forget just how much physics goes into making a good, harmonious song. Just like light, with it's constructive and destructive interference, you can have notes that either harmonize perfectly, boosting the strength of the sound, and the depth of the piece. However, the reverse is true. When notes just don't sound good together, they "destructively" interfere. They can sound incredible separately, or even one after another, but together, they just cancel each other out. Now, only the concept of interference works out that way for music, but you see where I'm going.
You have a great song here. It could use refinement, but in the way that my advice won't help much. IT needs to be fuller. You have a healthy sound, and a built to last style. But give it something more. You have the first three dimensions. Height, Width, and depth. But give it the fourth. Make it fill up a meaningful amount of time. The clip is great standing alone, but imagine this attached to a longer piece, maybe 4 or 5 minutes. If you changed the ending a tad, to make it flow with the intro better, it could be a pretty darn good loop. But you've got the talent for more in this. Work on fleshing this song out. It's a great test of the waters, but don't stop working on this tune because you've got a warm reception. Take this great idea, and pump every ounce of awesome you can out of it.
I looked forward to hearing your music again,
