In future please try to post your work to file hosting sites that can stream MP3s (such as 4shared for instance). Unless you have made a proper video to go with the song please don’t use YouTube as we can live without the pics of Akon and besides that the sound quality is terrible (even with the YouTube &fmt=18 trick).
Anyway…
I quite like this, though for an acoustic version I think you could do with timestretching the vocals out (slowing them down) a tiny bit because, for me at least, the piano sounds too fast and a little muddy for an acoustic version.
Incidentally, an radio DJ friend of mine was interviewing Akon and played him the Cosmic Dawn remix of Right Now with the intention of asking him what he thought of it. Akon wasn’t very happy as he doesn’t like unofficial remixes! Oops!
