And that is the attitude you should take, good work is good work and if you can only pick 3 out of 40 it gets hard to choose. If I didn't win a contest I felt I should've won, I would take it in stride because I look like a bigger loser crying about it. I look forward to what you come up with and how it turns out overall, just be positive and move forward to get what you want, take your losses and use them as fuel for the next attempt.
Edit: The Maiasaura is a good choice too, I am quite fond of it.
