Not a bad start . . .
It needs a bit of work though. The melodies were a bit off beat, you should probably get them a little bit nicer sounding before using them. Also, it was a bit incomplete sounding, I don't think there was much of a bass there.
Other than that, I did enjoy listening to the melody, and I thought you did a nice job with making melodies that sounded good together. Keep working on it and I'm sure it'll turn out nicely.
