Well you wanted some advice, critique, so i will start with the basics, and then we will see where we end up at the end. note: your FB links are not working
To start with it is always important for a singer to know where their tonal qualities and range sound the best. So knowing your own effective range is very very important. Also knowing your lung capacity is important. Especially with something like an audition, where you are GOING to be nervous/tense you need to be well inside your comfort zone, no matter how much you practice something just outside of your best range, you are likely to mess up when its crunch time. So select your music based on what you can sing naturally/in your sleep. To use an absurd example trying to sing Emotions by Mariah Carey would be suicide for the vast majority of singers, because no matter how you made the song your own, hitting that whistle register part is impossible for the majority of singers. So pick to your strengths/know your own strengths.
Which brings us to some more general advice, making whatever you will sing your own. It is not Karaoke, its about how you take an original piece of music and embellish it and/or broaden it. Judges dont want you to just sing it well, but to "make it your own" they want your personality in it. I think quite possibly the best example of this ever is the cover of Nine Inch Nails song Hurt by Johnny Cash. He didnt change tempo, just minor inflection changes and it went from a song about the pain of life, and addiction to heroin, to a song about the pain of life, and the burden of aging. So let your life and experiences come through in whatever you choose to sing, it will make it a far more compelling rendition. Picking your music selection based on something that means something personally to you is a great way to go about this, as you can show your emotion, and the trials you have gone through in a song while both doing it and yourself justice.
Some of this next bit will be something of a restatement of my first point, but it still needs to be said. Range is not as important as tone. Their have been several major artists both on the voice as well as on the radio that have a very very limited range, but have excellent qualities within their range. They dont stretch to what they cant do, and their for never end up sounding out of breath or out of tune. A great example for this would be the lead singer of The Cardigans Nina Persson. She has a one octave range, she NEVER goes for the high notes, she cant hit them. But she was still/is a top chart singer/songwriter. So dont think that just because someone has greater range, or certain tonal qualities you do not posses has a greater chance of making it than you. Work on and focus on what you do best, and you have a real shot.
If you want a less general critique, or more specific advice either ask for it here or in PM as i dont want to be seen to be "blasting" you. I do realize how hard it is to ask for something like this, and that any art is subjective. To add to that with only one song i could listen too(i wont listen to low quality for something like this for a number of reasons) and no indication of how far in the past that it might have been sung, any number of things i could say could be incorrect due to yourself having already improved upon them. So kind of as stated above if you want a more personalized critique then by all means ask for it, i just dont feel comfortable doing it without some indication from you as i would hate to be seen by you(or others) to be shitting on a dream that is obtainable.
