I have mixed feelings when it comes to Justyna's song and performance.
It could be a good song for Eurovision, it has potential to have a good staging and being liked by viewers, but personally for me it's kinda annoying and overwhelming.
This is not a song that I want to play by myself on Spotify, her English is just bad so IMO she should've recorded whole song in Polish.
She's like tenacious relative of Ruslana and Loreen in one pircute who tries too much and she wants to do everything that is needed to be succeed on Eurovioson in 3 minutes. We had this kind "too hard" performers in the past - Lazarev from Russia, many princes from Sweden etc... I didn't feel them but the viewers do.
BTW, Doda did an survey on her IG a few days ago with question about her song "Mama" if this is good for ESC. She said that she tries one time to be on ESC but former TVP's head and his wife (Kurski) didn't like her so she was banned. I think that she's trying to do buzz around herself, as always, but I like song "Mama" more than "Witcher".
