I guess its alright. I really liked the stringed instrument that came in around :56, gave it a good vibe, but you definitely could've given it a more complex part while still keeping an ambient feel. Even for an ambient song, it doesn't feel like there is much going on, its compositionally simple, and therefore a little boring. I'm glad you tried to mix it up at 2:36, but the manner in which you did so did not flow well with the rest of song. It just kind of went downhill for me from there. You could use something like passing tones or anticipations for variety, rather than just playing one note over and over. You'll get better, keep at it.
