Omar Naber is on stage now for Slovenia and while his singing was sometimes not completely on point during the first rehearsal, today he sounded very well during all three runs as far as I could hear in the hall.
The panel screens all around and above him are actual props and while they will look great on the tv-screens, they are a big disadvantage for the audience in the hall as anyone not standing or sitting right in front has a big chance of seeing this performance through the (at least transparent) panels during a big part of the song, as they only rise up just before the last chorus.
What I do like is how the lighting uses pyro effects without there being actual pyro. Another case of less is more, but well applied here.
