it has (what i like to call beginner) melody that goes E...F...G...F... etc etc.
i would say try holding the E of the pad over and over instead and change some other background synth or melody. and then maybe after the last half of the 4th repeat (14th beat), have to beats of F or G or something else.
just a suggestion, but i think it would go a long way. the pads and everything sounds amazing, it just needs a better melody in my opinion.
