Seeing everyone's works so far put me in kind of pinch.. I hope I could finish mine in time. XD;
Although I can't help to notice something..
Chuchuan, there's a glaring mistake in your back view. It won't be a big deal if you make the design symmetrical but wouldn't the broken jousting pole (which is on our left on the front view) be on our right on the back view? The armor's design is inverted as well so I hope you fix that soon.
