Yue Lingyun, this name is better. When read, it is smooth, loud, grand, and musical; when written, the strokes are simple or complex, well-proportioned, and the signature is beautiful. The artistic conception is also good, giving people a sense of being unconstrained, free and lively, and otherworldly. And it has rich meanings. The literal meaning reflects that the person is sharp, resolute, and unstoppable. As for not being feminine enough, I think the character "Ling" does show masculinity, while the character "Yun" conveys tenderness. This is a combination of hardness and softness, which is just right.
Yue Peiyao, this name is suitable for every lady or Xiaojiabiyu. It gives people the impression of following the rules, being more old-fashioned and less modern. Moreover, the font is also straight and stable, with many strokes and twists and turns, making it not smooth to write, lively and not good-looking. To sum up, it is recommended to use the first name.
