Just a quick scan from top to bottom:
Varangir looks weird, though the photo's angle might not be helping.
The two Blood bowl pics - Okay, I'm pretty sure it's an elf because pointy ears, but High, Dark and Wood Elf teams all look much different. Probably 'normal' Elf, but Androgynous Elf is the best I can make of it.
Troll pic: ... meh. Need different perspective on it. Wrists/hands look kinda weird on the arms.
Custodes: Joy, yet more good-looking Custodes we won't get to use in 40K despite Guilliman having turned them loose.
Vehicle doors: Look good, but they're only vehicle doors so...
Sicaran turret: Looks good, but I'm starting to wonder just how many variants of the thing they're aiming for.
Khornate dragon: Daaaaaaamn. Now that's a dragon.
Tau Tiger Shark: I'm not really a fan of the overall Tau look, so I'd normally just skip over it, but that thing looks like it lost a fight with a steam iron. I don't think the guns used to be that encased. I remember the bottom being the more interesting side to look at to begin with, and that's not a good thing - even for a flyer.
Middle-earth orc bits: Looks like they'll add a bit of diversity in larger Orc blobs.
Ask not the Eldar a question, for they will give you three answers; all of which are true and horrifying to know.
