One thing you have to learn as an actor is "Don't look back." You go in, you give your audition, you do your best, and then you move on. Don't try to second guess the director. You may have given the most perfect audition ever, but you may be taller, shorter, darker, lighter, etc, etc, etc. Forget the audition and start thinking about the next one. If you get a part, that's excellent. If you don't, you've already moved on to other things.
Sondheim said it so well in Sunday in the Park with George: "Just keep moving on".
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
