Very nice.
Except for the drums - I agree on that with other reviewers, they sound underwhelming. You can get new samples, or try to experiment with combinations. Usually, a clap combined with a snare gives a much fuller sound. Combine a bass drum with a cowbell at half the volume. Etc. This can even give decent beats in MIDI.
Otherwise good job and keep it up and whatnot, you're obviously talented and skilled.
