XayberOptics said it best
It's lacking a distinct melody. Perhaps something in the highs that takes all or most of the listener's attention (1:44-2:22 is an example of such a high-pitched melody, but it didn't work too well for me).
There's too much tamburine before the 2:52 mark. Either lower the volume to make it more subtle or make some variation through automations to make it less constant.
What I'm listening to now up until 3:44 is sounding too repetitive. As a listener I'm getting kind of tired of it.
Nice conclusion (with a little too much drum before it, making this sort of "chopper" effect that didn't really work out too well for me)
Overall a very balanced work (with the best part at around 0:55-1:20, where you showed the "personality" of your track), but it needs more personality and variation.
Nice job, nonetheless.
