The composition is pretty good - but I agree with most other commenters that variation of timbre (get to know your mod wheel on your midi controller or other light modulation of parameters over time with automation!) could have helped this sound a little less flat. Sometimes just putting an LFO with a teensy bit of depth on things like the filter or wavetable position of a synth can do a lot!
I do think you've got a lot going for you in the chords/melody, and the bassline was a standout part of this, so you succeeded there. Percussion is hard, and is a week point for me as well - I recommend studying and copying percussion parts you really like.
