The rhythm for the piano is not bad. I would very much recommend using a second or third pattern and have it change up when you want to change the mood of the song rather than having it be the same loop. I notice you did the same thing with the synth, I recommend also having it change on occasion as well so as to avoid letting this sound super generic.
The drum pattern is not too bad, however it seems like you mixed two different bass sounds for the drum kick which I feel is a bit excessive.
