the stereo spread on the keys are rather annoyingthe keys themselves sound out of tune and youre mixing scales so it just sounds wrong regardless. keys are also very loud (the entire mixing on the track could use work)
the hi hat rolls seem sporadic, which i assume you made the hihat rolls over 4 bars. try to limit unique hihat rolls over 2 bars for 1 section of the song
the melody never changes and gets hard to listen to after a while. try to make different melodies and dont be scared to push past 4 bars for a melody and include other sounds and synths to make it sound more fun and interesting
syncopation and ornamentation at section intervals can also help with melodies (along with breakdown sections where certain instruments can be added/removed)
808s dont seem to compliment anything and the kicks happen way to often, nullifying any real punch or significance to any of the kicks. there is also a lot of mid/mid-high on the kicks which is slightly annoying (atleast to me). i would lower that mid/mid-high on the kicks in an eq and raise the bass (50-100Hz region)
in general everything im hearing sounds pretty stock (presets and instruments wise).
the airplane police call thingy seems to disrupt the tone of the song in my opinion. i believe there is definitely a way to improve on that in a way that you see fit for the style/type beat that youre going for
take everything i said above with consideration and also keep in mind that its just my personal suggestions, as i could be wrong about everything i said as well. do look forward to seeing more by you though!
