Yeaa!@!!
It's not 'too melodic'. In fact, the melody is really great, it fits really awesomely.
Since its drum and bass, I think you should pump up the drums a bit. The bass can do some toning down, its a bit too loud. In fact, all the instruments apart from the bass should be a bit higher.
I love the melodies. I wish I could make something as awesome like that... =/
Great work!
