Is this a good idea for a sweet sixteen?

Ok, I'm having my sweet sixteen on January 29,2011, but I am meeting with my party planner in a few weeks and I wanted to know how fun and cool my idea is! It is jungle themed, so I am going to have blow up, home made, and real palm trees everywhere. I am going to try to have real like and stuffed animals like tigers, lions, birds, koala bears, etc. placed around everywhere to get the "jungle" effect. I am also going to try to get the zoo to let me have live animals, like a snake, maybe a tiger, giraffe, a monkey or something big like those to take pictures with. (I am having a photographer there, too) I am having the most popular teen/college DJ there, cause he is my cousin, (lots of people that I have already told are really excited for him to come!) For my cake, it is going to be three tiers (levels) and I want the first level to be brown with palm trees, the second to be tiger print, and the top to be zebra print. My invitations are going to hopefully be pop-up invites, but if that cost too much we might just do some on vista print. I am expecting to have around 75+ people there. The venue is pretty nice, but I will have a lot of freedom to do what I want. Do you have any other ideas about anything? Entertainment? Does it sound fun? I will appreciate all comments! Thanks :)
