i like the intro and how it builds up slowly till the drop..also the main bass sample is nice...
the synth that enters at 0.55 is a bit in conflict with the bass line..
the piano at 1.30 is really robotic, static and the melody quite boring to me...
the drums are not bad...snare could have some more body and some hats on top would be great
nice progression in the intro. Like how you slowly bring in more elements. Love the break too. Some fx may help the drop be more climatic like a sweep or something. I agree that some hats / cymbals may help thicken up the break. Like the bass kinda has a subtle jump up vibe to it - pretty original sounding. This is a good start. Try layering the break maybe and add some fx maybe some vox too.
Drums are crisp and punchy. Programming is grooving. Synth sound is a little cheezy IMO but if its what your going for its cool. The synth at 55 is out of key with the other synth and is conflicting just needs some EQing and maybe some filter screwing. Melodic idea is alright but needs variation. The piano is very 4/4 and not very interesting as it is following your main melody and should be doing something other instead. Play with some velocities on the snare and the mix could use some reverb at a whole. I like that reversey synth and overall this isnt a bad idea at all. Keep working it and get some more melodies in there with the piano and even some strings and atmo.
