The hauberk thingy looks great and you definitely have the looks for a Clegane, but I´d weahter the plate stuff a little more, I always use some acrylic colour with just a little water, paint the piece, let it dry a bit, and then rub it off with a cotton rug or something like that, you could also use blackwash, some stores sell colours like that.
And maybe it´s just me but I´d love to see some scretches and dents in this armor.
