Well about armor, I tried to make some kind of shirt above his plate mail, but I will continue. Wait for next modification. If you want to know to see his portrait just look at my avatar.
I hope you continue...it's a good skin--around the face. Only the face is really nice. You could work on the armor. It's a bit too smudged, blurry, and/or plastic wrapped. Oh, my bad, the sword's sweet too
About the chest, I tried to make a cloth which was worn by knights above plate armor in middleage. What to say, it my first experience making metallics and clothing, but i will modify it soon.
