It seems Estonia was having some trouble with their staging, or rather the camera angles. They play with shadows and yes, nighttime skyscrypers reappear in the backdrop. The shadow play seems to continue throughout the song and a lot of shots from above are used. They do clever things like Stig staring straight at the camera while Elina avoids eye contact. In the end Stig disappears to the darkness while Elina is left alone in the spotlight.... This might turn out something awesome on screen, can't wait!
