What do u think of my singing? I have theater auditions Thursday. I know Im not the best, but what do u think?

You're not horrible at singing. You CAN sing. The problem that you have is, you tend to go "flat" on some pitches while singing. Going flat can alter the song, making it sound less than good. You know? So to help you, think "above the pitch". Also, in your Maroon 5 video, when you sang "She willll be luh huh huhved", take away the 'h' sound. When you're singing the word "loved", always keep an open mouth like you're saying the word "ah". You should sing 'loved' more like, "laaaaahhh ahved". The descending pitches while singing the word "loved" should be smooth without the 'h' sound interfering. Hope this is understandable!
