For my tastes, I think the melody is excellent yet it could do with a smoother and softer opening than just inserting into the main melody at the start. How should I put it... it's like getting out of your warm bed into the cold and into a warm shower. Knowing what the song is, you'd expect something drastic or something that follows its key sound. As it is, it's in the midway.
Don't get me wrong, it's a great start for a remix but a smooth opening would be something to work on.
Good work otherwise. =D
