as a massive arms and armor nerd there are a few things I could nit pick at. Overall it is really great stylized character and your sheen you put on the metal is good and you have a handle on the lighting though a few nicks and scratches might give the armor a bit of character and indicate some usage to it but that's what I enjoy when I render metal for armor. the things that stand out to me are on the sword pommel, I think it ought to be thicker as a wheel pommel instead of being flat. I would also bring the breast plate a bit higher so it sits on top of the hips a bit more, coming from a practical concern that it would make it easier to move in as historical armor generally has the breast plate come down to just below the navel line that then often will have an attatched fold (the flaring skirt part), so there's the practical part but I also think it tends to look better that way personally.
All in all it's REALLY fun and I like it, it may sound like I was getting nit picky but it's hard for me not to ramble and get that way with armor as it is one of my personal obsessions.
great job keep it up, I wanna see this one finished!
