The melody's decent, there's room for improvement. Also, you should try making more than 1 melody/ The major problems are the instruments you chose, specially the bass. Sounds too distorted and plain, should make it deeper with some effects. The instruments you used for the beats were ugly too. You could make this song better by fixing all those things, keep it up ;D
Mind checking out a WIP I just released? It's called ".:Wherever She Is WIP:."
