Hogwarts Triwizzard Tournement

Before I found this I thought I would never afford to have all these Harry Potter sets, then I did see this and stopped what I was doing immediately just to win all these sets. I worked hard to make this and yet I still feel as if I could add on. I really enjoyed building this. If I loose this I will never have all these sets. These are all I want right now. I guess I should explain it. Pic 1 = Big view. Pic 2 = Task 1. Pic 3 = Task2. Pic 4= Task 3. Pic 5 = Grave Yard. Thank You.
