Admittedly, I'm not very good at critiquing armored peoples :X I think they both are looking good so far. Something is bothering me about the guy's neck. I don't know what exactly, but it seems like it might be uncomfortable with the neck armor twist his face/head that much away from the way his torso is facing? But I could be completely wrong, cause like I said, I'm not very good with armor!
I really like it so far, though. Hope to see an update soon!
