Honestly this reminds me of the Going Under soundtrack especially how the song started off. Which is a great thing! Highly suggest you go listen to it! It's simple enough not to be distracting which is nice. HOWEVER, I think you could add some more "charm" to this. Maybe a few instruments to compliment the simple tone a bit more. Some fading pads perhaps? But for what it is I think this is a great start!
