Yes
It doesn't start as subtle as I'd expect this kind of ambient piece to begin. I think a simple filter fade or something would add to the atmosphere at least a little bit. The whole piece feels a bit confusing since it starts so quickly, and in the first minute you just add and add and add instruments. Since it is after all ambience, it's fine to stretch it out a little. Little happens the last two minutes anyway, so it would feel like it's progressing a little more if you had a little more space between the introduction of each "instrument".
The track generally doesn't flow too well. The sound quality is clear enough, but the sounds are sort of sitting on top of each other, and none of them really stand out. The biggest problem is how it sounds like all instruments are going at individual speeds. Check the rate of all LFO's, make sure they are synced with the track and keeping somewhat similar rates.
Other than criticism, I really like some of the sounds. The rather high, almost organ-like pad provides a dramatic effect, which to my ears could symbolise fear or a similar mood. If you emphasise that, it would fit great for a dark, suspenseful scene in a movie. The instruments fit very well together to produce an atmosphere. The only thing that disrupts this atmosphere is the high frequencies of that "buzzy", automated synth.
I'd say overall it sounds like a complete piece. It doesn't have any melodic theme at all, so I don't think there is much more to be done with this piece. Since it does neither have a recognizable theme or progress much, it will fit much better as subtle background music than a typical music fix.
