This comment goes back to scope management... is it wise to do two beauty shots of an outdoor environment that do not incorporate the focal object? I'm guessing the tower of kick@ss is the focal point of the first shot... the second shot?
Also if you do something that is so open ended, you run the risk of not being able to frame the shot in an interesting way... wide open spaces with a lot of particles is also very expensive for a game environment... Unless you make it very flat and low res.
Could also run the risk of confusing the theme somewhat.
I really dig the thumbnails from naza.. the composition in them is much better than the composition you've chosen for your final beauty render.
Let's see some 3d though, for reals.
Generally a good idea/theme... interesting level of chaos going on as well.
