Oh, I remember this. Reminds me of Wonderwall -- probably the style of delivery and the relative chord progression. Good for a demo, but the mixing and vocal delivery are your weakest point. If singing out in that range is hard for you, I'd just capo the guitars, and port any electronic instruments into the right key. Vocals need harder compression. Track as a whole could use less reverb. I'd like the guitar doubletracked in the left and right with a chorus, the drums panned a little better, bass centered.
