Okay now we know why most of the mens are skinheads in the game…
because of the chainmail.
Its easier to put the chainmail on if you have no hair. 
Two comments about the armor and clothing.
1. Why looks the blood on the armor weird?
Because the blood is only on the part of the clothes/armor you are hitting with your weapon!
The blood must come for the body of the enemy. The chainmail must also be bloody and the gambeson beneath.
At the moment it looks like the blood is seeping through the plate armor, but everything underneath is clean.
2. Head damage!
There are differnt body zones where you can put armor on it. But the complete head is only one zone and that´s a problem. Most helmets let the face open and without cover. There should be a differnt zone for the face!
At the moment (beta), it makes no difference if you hit your opponent on the helmet or middle in the (uncovered)face.
You can test this with arrows in the beta. If the NPC wears no helmet, you need only one arrow for a kill (if you are strong enougth). If the NPC wears a helmet you need at least 2 or 3 arrows into the face (or the remaining head).
If the foe has no visor, you should be able to kill him with only one arrow or one stab into his face!
(It looks weid if a NPC attacks you with 2 arrows in his face.)
