Austria: Mediocre song, good voice, horrible outfit, "meh" stage show (which is to say none). Possible qualifier. Reserving judgment.
Estonia: Like Austria, only with better clothes and at least an attempt at a stage show. Feel good. Will probably qualify.
Slovenia: Tonight's first song with an actual stage show. Pretty good one, too. Competent vocals, OK song, good stage show. Bonus points for the Swedish. *QUALIFIER*
Croatia: They've kept the worst part of their performance in the national final: Mostly singing to each other and looking into the crowd instead of trying to connect to the TV audience. This will cost them. It's all very wholesome, beautiful and melodic, but also very detached. I don't think they'll qualify as of right now.
