Whoops! Sorry you didn't understand the reference to the Phoenix. It doesn't matter anyway, but about the 3rd bottom image:
-The guy's head is slightly too small lengthways. His helmet of plate, I assume, is thick, so in proportion to his body, without his armour, this guy will have quite a small head compared to other models of his size (unless his chin is in his gorget). But this is very subtle; maybe you meant it to be that way. It's not a fault at all, but the guy just doesn't look like the average human for his size. In a way, it looks pretty cool, as most of the humans bodies' proportions are the same old, same old when it comes to GW figures.
