I really like the look of this, I really do! The problem is that it's extruding too much from the chest and would clip with the arms when holding a weapon. Many chest armors already clip with the arms, but those aren't as noticeable since the arms usually cover the chest armor up. This chest armor, on the other hand, would straight-up clip through the arms.

My suggestion is to swap the chest armor and the syandana, so the hilt is in the back and the blade is extruding from the front, albeit not as much as it currently is from the back.
