I accidentally sang 'Cow' instead of 'Mountain' in Korean... fml.

My vocal eval was today and I was so nervous that my pronunciation went out the window. I literally mispronounced the batchim and the judges chuckled.

I wanted to vanish into thin air. lol. Do u guys think they take off major points for bad pronunciation if the tone is good? I feel like I just ruined my chance of being in the "vocal line." Should I re-record a demo and send it to my manager or just let it slide?
