This has got a real nice mellow vibe to it, but even though it is an ambient track, I would try and bring the drums out a bit more. For example, the kick drum sounds just like a bass kick by itself. Personally I layer my drums quite substantially, meaning the kick sound is usually at least 2-3 separate kicks playing at one time. This allows you to have the bassy kick you've already got in place, with perhaps a higher, snappy kick to bring the top end into play, then add a standard flat sounding kick to give it some sound in the mid-frequencies. Likewise, I do this with snares as well so the snap has a top, mid and bottom end sound to each drum hit. Once you've heard the difference layering makes, you'll be amazed.
