Too much bass OR volume causes disortion. This song is an exampkle of such thing.
The drums are too soft, needs to be compressed, but not too much of course.
Some sounds seem to be a bit... erm, questionable?
I think the ending was a bit abrupt.
The piano melody seems to be going too fast - thats weird because at first it seems to be fine, but then you realize that its just spamming on the keys.
Overall, needs improvement. Just keep up the work.
