The lead sound in the first 8 seconds sounds dry, it could use a chorus effect or reverb to make it more involved-sounding. The melody, while okay, only has notes on each beat and it feels kinda like it's sitting still, there's no much movement or change of rhythm (I can't explain it perfectly). Quite short tune, so there's not much feeling of progress but I do appreciate the variation every 4 bars. Nicely done, but there's room for improvement.
