Skype is an innovative idea of teaching piano!... though we may have a time different issue here. We're in London while you're in Texas.
Anyway, we made the videos:
They're not perfect and my daughter is still in need of more practice 
Please provide some feedback in your convenience.
Thank you very much.
The time difference will not be a problem at all for me. I used to live in France so I have an idea of the overall time.
I am usually free in the evenings your time, and during the week of March 15th, I will be free at almost anytime.
Now onto the videos:
To begin let me say that for her age and the amount of time she has been studying she plays very well.
This said a few comments/suggestions if I may:
1. her fingers should be a bit more curved.
2. I would tend to agree with lostinidlewonder about the sitting.
As a recording suggestion, next time would you possibly be able to record her from the side?
3. The Bach does need metronome work. If you have a sophisticated metronome that allows for different rhythms, I would put the sixteenth, otherwise the quarter will do. Just working with the metronome on a daily basis will improve her and the piece quite a bit.
4.Concerning the Arabesque, the first item to deal with will be again the metronome. The sixteenth need to be equal. Also, she should think them as leading toward the eight note. I would tend to agree with lostinidlewonder that is not so much finger work(although finger articulation is important), but more like a small phrase , going from the 1st sixteenth to the eighth.
The next thing is dynamics. Personally I could use more difference between soft, loud, if at all possible.
Personally, living in the USA, I have no idea about the AMEB levels, however as a teacher I would rather for my student to play pieces they have worked on and feel comfortable playing, instead of starting to work on a new pieces within a few month of the competition/concert.
Obviously this also depends on when the competition is.
In addition, for me, giving her level, I find the two pieces chosen to be appropriate.
We want for her to enjoy doing this competition and have a good experience.
Hope this helps, and let me know about the Skype.
I am leaving tomorrow and I will be back on March 7th.
