Azuma Toh's original concept design for Fate/Grand Order's Shi Huang Di (Fate), seen in post #3338439. Quoting Toh, she said, "On a side note, when I first received the offer to draw Qin, I had imagined he would be a man with an intelligent sharp eyed look as illustrated below based on his previous descriptions. However the design order was a 'fully-naked androgynous fantastical beauty', so this was rejected within an hour."
Toh's original design for Shi Huang Di has him more in his mid-30s to early 40s, possessing a mustache, hair tubes for his sidelocks, wearing a Mian Guan, and a robe with intricate patterns on the collar.
