I like a lot of aspects of this. I like the more trippy drum loops your using, and I like the piano melodies in general. Also, I feel like the rising pad-like strings work really well as background support.

For constructive crit., a few things. 1. Personally I would like to see more variety in the drum patterns. I think you use two throughout, and where as they both sound good, there's very little deviation from them (This is a big preference of mine though, so it's probably not as important to other people). 2. You have one synth that occurs a couple of times that dominates in the right ear (2:04). It's kind of loud (especially in headphones) and detracts from the rest of what's going on. I wouldn't suggest removing it, just lowering the volume.

Good work overall tho.
