I really love the slow buildup of this track. The instruments use the stereo space so nicely, just as I've come to love from ambient music. I think when the percussion comes in, its rather lackluster, the snare doesn't seem to fit into the mix. Near the latter parts of the track it also starts feeling over compressed or limited.
Overall however, I really enjoyed this track. It flowed nicely and left me feeling content. Great job, i'll be checking out more of your stuff :D
