alrighty
the bassline from the source is established as the groove from the get-go, and there's no variation to be found until 2:44 (aside from the pad breaks and piano section at 1:00, where it's not present). as more instruments are layered in, they just follow the same groove. change up the rhythm every other or fourth bar, add some unique fills or an original melody on top. it's not engaging enough - it needs something to keep the listener interested.
2:39 is a nice change of pace, but after it breaks down it just builds right back up to how it was, with a different groove. maybe try to introduce some more new instruments there to keep it fresh.
3:45-4:02 - good texture here, this is my favorite part of the song; it doesn't seem so grounded by the bassline during this section. cool drum choices, and the piano sounds nice.
also, i feel like there's some headroom for volume.
one thing to stress is that i think you need to find some new sounds or try out some different styles. i get this bland feeling from your music (hate to put it that way), and i don't think your sound choices in general are the most accessible to the average listener. hope i haven't been too direct with my crits - seems like you've got the chops but some things just aren't quite clicking yet. you can only improve, so keep working at it
