repetitive
adding some extra parts instead of repeative parts over and over again, i do quite like however how the bass is a less dominant feature as it sounds just right here, as it is commonly overused in a fair few songs.
the best thing to do would to look at other submissions and check out whats happening there and try to use their ideas in your songs, just get a feel for the style and balance between bass and treble, somthing that's often crucial for a good song, but i think its been done well here.
for improvement just make it less repetitive.
