Tweak my T&Y (linothorax/spolas) pattern, ca 500bc

[Giannis K. Hoplite]

I think that it's the pteryges you should shorten a bit. Also,i think that you should completely rework the pattern of them. I think best that they are cut in one piece. This piece should be straigh,because when the body will be folded and tied,the lower hem will naturally be straight. The pteryges however can naturally open (this is their purpose),so there is no need to be cut with that curve.
Christian made his pteryges in different sections,like you plan to,but he now plans to replace them because they don't sit well.

Another suggestion is to make the neck guard a bit higher. Also,make the back flaps longer and narrower. It might be advisable to make the shoulder flaps also slightly longer. And it's better to make them a bit bigger so that you can trim them down if necessary,than too short.
