Hmm - Im seeing some stuff that are ......
1. OK - first off man - this piece was a tinsy repetitive - word of advice - at the beginning bring a little of the melody in - then progress toward the main melody = this build up momentum AND has a nice effect to listeners. Plenty of ppl do this - Armin, Vol, Kandi, its a great trait to have man.
2. DUDE - that first pluck - was really overused - in the intro u had it playin, and end, (im guilty here too) its better to add a different pluck at different points - I highly suggest listening to "Ex - drivers remix of Vol Deemans Fantasie" in that one piece he progresses easily with two main plucks that get the melody going - its pretty cool man. Instead of using one pluck in the intro and end - use one in the intro then in the middle use another following it up with the last in the end.
3. Emptiness - this happens a whole lot man, one thing that gets ppl is relying on reverb to fill empty spaces = not a good idea at the beginning. My advice add some spice by using some precussions like hats, and claps ( i heard one - but it was pretty low).
4. Transitions - when u use one add some delay man, becuz if u dont it makes the piece sound pasty = not good. ( U know that one at 1:10 - yeah add some delay and reverb to that )
Well - these are all suggestions - not tryin to be bossy, hope u get that down man.
