I am not so sure that this will win, the song definitely grew on me (it was initially top. 10 but now it's rather top. 3 so I wouldn't mind a win), however the performance is lacking a bit. To sit and fake play a piano for 3 minutes is not really exciting, the song is more dynamic and could use of a bit of "drama"... don't get me wrong, it would be out of place with some banal flying angels or mirrors (pun intended), but still... something? Maybe like staying up in the last chorus?
Vocally he is great though and he does captura his audience, wish there were just something more happening... not necessarily around him but with him...
