Wow thats amazing! I'm quite an amatuer and I am actually currently in the process of making myself a Wang Yuanji costume, and WILL make a Sima Zhao for my other half too.
I just have a couple of questions if you dont mind me asking.
1) What did you use for the detail on the "neck belt" as I call it and shoulder armour?
2) for the rest of the costume how did you get the gold and black i.e on the bottom half of the coat? My thought was iron transfers? (I am thinking of doing that for mine)
You say you used craft foam for the shoulder armour? Wow why didnt i think of that, I was going to use leather for mine I'd probably use leather for the 'neck belt' now xD I hope to find a large enough sheet of black craft foam x3
As for the detail wow I know what you mean by it is a killer xD
All the details on the costume were hand painted. The insignia's on the belt and such were 'potato stamped' basically i cut the design from craft foam and stamped fabric paint onto my pieces before i assembled them then touched up with a brush and fabric paint.
you could do iron transfers as well it would be faster. but i painted because the details are so small it was a pain for me to even think of that method haha!
most of the large pieces you see were smaller pieces joined together. its a matter of hiding the seams with hot glue
