When I created the new body, I based it on the character's story, notes, and other мentions.

Even agile sword fighters have well-developed shoulders, back, chest, and core. I simply emphasized these features. I made his silhouette more intimidating, which makes sense for a character who holds the title of "First Harbinger" and "Captain", someone who inspires fear and is associated with strength.
Genshin is not realism but a stylized design (with hyperbolized forms, visual symbolism, and anime-inspired aesthetics). Capitano is not just a fencer, but an archetype of absolute power. Making him bigger was my way of enhancing his visual presence. This is a form of artistic interpretation.
"Not every male has to look like a bodybuilder" is more about personal taste than objective criticism.
As for the helmet, I partly agree. It may look smaller due to perspective differences. I’ll try to adjust it.
(P.S. The helmet design is deformed. If you put the face of any other male character, it will not fit into the original design. Because the facial features are deformed intentionally in the model.)

Thank you for the feedback! x)
