Not bad so far, of course it's still pretty early in production to really give any feedback, however, as far as the intro is concerned, It seems rather minamalistic. I can appreciate a little minimalism, however, I think you can add a little filler because the song loses my attention before the vocals come in. Also, maybe fatten up that synth, or add another synth that can play along with it to add color. It's a very catchy song to begin with, so if you can nail the synth melodies with some good drum and bass work there's some real potential here.
Now that I think of it, this song is missing a good deep bass synth to drive the rhythm.
Also, i don't know if this is the kind of style your going for, but perhaps it's worth a listen?
