"On Tuda's face, a tinge of disappointment was visible, mixed with a wry smile."

Explanation:

"Tinge of disappointment" better conveys the nuance of the original Japanese phrase "淡く盛り上げられた失望の色", which suggests a faint or subtle feeling of disappointment that is somewhat concealed by the wry smile.

"Mixed with a wry smile" is a more natural way to express the idea of a smile that is tinged with disappointment. "In a little pile up" doesn't convey the same meaning in English.

I also rephrased the sentence to use third person pronouns, as requested.

"A hint of disappointment, tinged with a wry smile, could be seen on Tuda's face."

Explanation:

"Hint of disappointment" and "tinged with a wry smile" capture the subtlety of the Japanese sentence.

Using "could be seen" conveys the idea of the observation being made without implying that it was intentional or deliberate.
