what is the instrument/effect in the intro? i like it a lot, i want to steal it! haha. i could do without the whistling, IMO. Vocals out of tune too much - unfortunate because you have a great sound to your voice. Particularly the word "space" rings nicely in the first chorus, but I'd keep the second note longer rather than coming down with it. THe final note you hit in the word is a bit off key. It could've ended on the previous note and sounded fine. could do with some arrangement reworking to make it a bit more familiar to listeners (just an idea). Great lyrics and i love the mix of electronic and live instruments - you pull it off nicely. I agree vocals could come down a bit - i want to hear the instruments as well, as there is a lot going on.
this is really one of my favorites i've ever heard on this forum. great tune. just a little work, IMO.
