the melody gets repeated to much, when the lead comes in its better...
but when the lead comes in, the volumes of instruments arent tuned to eachother well enough. this makes it sound like there is something missing (dull). you can fix it by adding a multitone filler sound, or really adjusting the volumes to eachother.
also the drum loop doesnt change when you cross over to certain moods in the music.
i almost couldnt make out if you were using a wobble or not... anyway
make it more wobble, and then play with different rates.
here's an example of a wobble used very nicely:
