It is sound design after all, and you have to tell us what you were aiming at... For example, I saw the stadium as a defenseless animal that people just hunt down because they're afraid of it when it just committed the crime of being big and not aesthetically pleasing. It made sense to me to insist on the whipping explosions along the pillars and the deformation and fall of the structure. It might not translate so well in the finished video but at least I enjoyed doing the thinking...
But in general I would expect a sharper attack for the explosions and a tad more of content in the mid-lows.
I also believe that the fall starts earlier than when you actually notice it appearing in the picture. I found that just about nobody saw it that way.
Finally, none of use has treated the back side of the building that we don't see. You seem to have a lot of free space in your mix and you could consider including that too.
I'm not a good critique, am I? :D
