The drums aren't bad. The snare could use just a bit of tuning. Maybe, with some EQ the snare could be brighter and have more presence. As for the melody, there are parts where it approaches a jazz feel. These are the parts which are most successful. The rest is kind of atonal and odd, and while theres nothing wrong with that, certain parts dont fit well. For example some of the bell sounds in the beginning and the louder organ parts. The bassline also could use a different sound. EQ here could also make it sound more beefy. You should experament with different instruments and effects to get rid of that stock feeling. Add a little something extra with each track you make. Thats my advice.
