I'd say Toby and Dilana should be safe for tomorrow. Dilana lapses into raw power screams at times on the high note climaxes, but that won't cost her yet, if ever.
Storm was the weakest tonight even though some of that was out of her control to some extent. That song forced her to take on another singer to do the male part. Although maybe it just put into sharp relief that she is not outshining the others at this point.
As for the rest, I thought Lukas was good, but both he and Magni didn't really close out the songs completely. They just seemed to run out of focus and air by the end. It is a minor point, but they should watch that and for that reason, they should get sent to the bottom three tomorrow. The fans could drop Ryan down there as well. I didn't really feel the changes to the Clocks opening, and his antics during the song seemed a little overwrought.
