To be honest, I think they're a little disappointing (sorry to burst the bubble) everything just seems very flat, Take the pavilion for example, it appears to be (although it might just be the screens) all just one flat plane, the side bits anyway. I appreciate that this could have been because when you originally made the stadium for the old engine you had poly counts etc to worry about, but I hope you can make it look a bit more 3d for the new engine.
Also, if you look at photo #3 the roof appears to be floating above the rest of the building. I also hope the pitch and outfield textures are to be changed, and the crowd does need improving atleast a bit before the release, so the game looks atleast slightly realistic.
I know how hard stadium making is and I think you've done a good job, but I want this game to be GREAT! However, bearing this all in mind, remember what this game is about: GAMEPLAY OVER GRAPHICS
I'm a big fan of this game and really loving the progress we've seen over the last few weeks, keep it up!
