It would be cool if something really big happens in the inside of the Chuunin exam, then a slight effect happens in the extrior aswell, for instance, someone summons a giant summon or uses a giant suiton which floods the entire arena (Yes I know these are genins, but Sauske and Naruto are genins and so was Garra XD) Other then that, I really loved the second part of the Chuunin exam, the best I ever seen.
