This is not that bad try to work on the kick mix may be add a sidechain with the other channels. The sub on this track is a bit over the top. You could add some fx sound and percussion on the piano solo's so it would be a less boring. The growl during the drop doesn't come out good, try to balance the audio with the other channels. I hear also fl studio default samples, try to download some sample packs on google ;) these were my advices keep it up
Thanks for the review! I will learn how to make different drums, as I haven't gotten to that yet, and FX and mixing are next on the list. I will work on abolishing default samples.
