Sounds better than most of the crap on this site first off...
I have mix ideas and suggestions but really if this had vocals few of them may matter. The composition is nice and the song goes somewhere. The gripes I would probably go into are that ...well, one the left guitar is kinda hashy compared to the right which is not bad but panned a bit too hard. And also, it's waaay too short for the instrumental it wants to be. Some of the drum editing in the beginning is too obvious. The snare could be whittled down a bit more to fit in better.
Ect...I am putting lyrics on this for fun...whether you like or not. In fact I am almost done.
