I like the new grey look you've given Saul, though I do have one or two issues with it:
#1: The green eyes are FAR too bright in my opinion, they don't look at all natural.
#2: The 'badge' on his chest seems very brightly coloured too, almost like there are little LED's in it. ^_^ I'd consider making them less bright, personally.
Aside from that, looking good!
