I'm not sure who needs the help here.
Its VERY good that its just you and the panel. As Dimmreaper says you can be yourself and you're not having to compete to be heard or put your personality across.
Serious note, keep the dress professional, dont look like the office vamp. If the panel has women on it they're not (normally

) going to appreciate your chest grinnning back at them. Possibly the wrong first impressions?. It might even distract from your answers and all they have left at the end is a pleasant memory :clown:
