Alot to look at, admittedly, I'm not all the way through. A few things that struck me though.
Fourth Bio in the very first set. I love it, very smooth, unpretentious in a way. Alot like the P1. The one marked "Tiger" Love that bio. ;> Also there's an image early on of a layered CPU gauntlet that slides open, rather than the flip top. Such a simple thing but it makes the design so much more sleek. The entire Anubis design is just awesome. Yeah, now I'm almost rambling.
I see a recurring theme in chest armour that looks great too, the half vest style that covers the pectorals and leaves the rest open. Sure, not super practical if you actually need armour, but it's appealing.
