Nice job! Instantly recognizable and a nice way to get a lot of the features of the real stadium stretched into a scale that works with minifigs and still doesn't take over a room the size of Brickworld. :) I like your flex-tube idea on the grandstand lights ... I wrestled with how to do these myself and must have built them a hundred different ways; I like your way better!

This is absolutely outstanding...very well done! You should contact the Lego people and see if they want to make a set out of this...I think it would be a popular gift.

Nice!
