I agree with thehatofwin for the most part. I can see Untitled though. Network is definitely my favorite. Untitled needs some more texture maybe. Methane doesn't really have a focal point or any object to attract attention. If this is an effect you were trying you should try the effect with an elite or spartan and see what happens. Just keep playing around with effects, and when you find one you like then you can try for poses/staged shots etc. The best way to get better is messing around with theater, so keep doing what you're doing. Hope that helps.
