Keep going!
It sounds like you, sir, have just discovered the circle of fifths! As beautiful a chord progression as it is, it would be nice to hear you develop your ideas further from there! Keep going, because it sounds like you're getting into it. It's nicely produced, you have a nice tone and a very ambient reverb... it's nice to listen to. I've given you a six, because you can take this so much further!
Hope this helps, keep it up :)
