I really like the vibe you're going for - they're fun to listen to and I think the melody is solid.
A peace of feedback that I have for this would be I felt the drums were a little overbearing on the melody, so bringing the drums down a little bit might help it stand out. Additionally, I would've liked to have heard some of your ideas fleshed out a bit beyond these 30-ish second pieces.
Other than that, I enjoyed what you created. Hopefully we'll get to hear more of your work in longer pieces in the future. Keep up the good work :)
