Here is something I through together the past week. Let me know your thoughts.

 

Some sections are too long (you could cut the first two in half each and it'd probably work better), the transition effects such as cymbals and the introduction of other instruments feel a bit awkward.

It decent, there's growth, a melody easy to remember, most sounds play really nice with each other. Lots of build ups that don't pay off or resolve in a weird way, so it ends up feeling like when you're about to sneeze but you won't, so you just half-sneeze for a while.
