I tried doing what I could with the score, I mean it's not really 0.84 stars quality :P
So here's some of that feedback. Hm...what I think you need is some more variation. Not in melodies...no. I'm thinking in instrument use. You've actually got some pretty good ideas here, but there is an overall feeling of disjointedness throughout the whole song. Kind of empty, too.
Try to work on your transitions! I do see that this is WIP, so there's still plenty of room for improvement.
As for your drums, they sound too loud, too, specifically the snare. Or just the snare, actually. I'm terrible with sound design and similar things, but I can recognize that there could be more tone to them, too.
Your bass gets really weak after 1:25, and I think it really adds to the emptiness of the song, considering you have just 3 sounds going on- drums, bass, piano. If you want to stick with the drum n bass category, put that bass back in there!
Based on what you named this .. "piano thingy", I think you are well aware that this is nothing close to what you think you are actually capable of doing, or at least you know that there is much more to be done to this piece. Right now it sounds like a dump of good ideas hopelessly glued together by laziness and/or lack of inspiration.
Make those good ideas stand out! Try adding something in for harmony, bringing back that bass, and just making everything *flow*. Also, effects! (I am very bad with this) Effects can really make simple stuff sound even more amazing if done right. So fool around with those!
