MHY usually nail it better with the female wuxia/xianxia designs (like Fu Hua and Li Sushang) but for males by far they only did Dan Heng, Blade and Jing Yuan so perhaps they want to try different approach.I think their designers changed as their new characters, be it GI or Star Rail geared towards a yin style of handsome for males or just go for shotas.

Normally a character with his type of design have long and bigger robes with long sleeves (think Taigong design in FGO, or the 公子 type who wields a fan and talks like a loyalty, someone like prince Duan Yu in Tianlongbabu), but because the sleeves are detachable (like Lobo said) that it ends up leaning more towards something a xiannu would wear instead. I think it's the contrast of his personality and his fighting style with the design, especially due to the detachable sleeves.

Makes me wonder if I'm too old for modern designsI get what you're saying actually. Dan Heng's original form has a perfect proportion and so is Jing Yuan, but new Dan is just queer in my opinion. It's just too feminine and too tiled to the yin style of handsome instead of the yang style. I like Wuxia and Xianxia since I grew up reading them, but MHY's design makes me feel very uncomfortable.
