If you notice here on the image, the character hold two wristblades, but the left hand is bare with only a leather bracer. so these blades are separate weapons and not parts of the forearm armor.
I'm working on the real version of the armor now. it's not a full body I have to do fortunately. the poncho, the shoulder plates, the right forearm and a leather bracer for the left. and the clothes folding out of the belt. I will use a Bethesda shirt that have sleeves fairly close to the design and will augment them so the shoulders sleeves are even broader to achieve the triangle form they should have.
I will also do the utility belt for the waist, and the pouches will be held by a very wide leather belt (jedi like).
the tights I'm not sure if I will leave them bare, I think it would fit. The calves will get armor, high over leather boots.
