First off have to say that I really like the first four note figure of your melody (E-F#-D-B), that feels to me it could be a great motif.
Since the beginning of the melody works so great, i was a bit sad you didn't have a lot of variation to the melody, but the track works as is 😁.
If you ever expand on this with more tracks, would highly recommend trying to use the first four notes as a motif, since that's some gold material IMO 😉.
Good work!
