Thank you!

I know that I am not using 'Yet' in the correct context. I simply don't know how else I can express the thought in a truly English way. ))) In other words, when the subsequent sentence has a meaning of a slight opposition to the preceding one.

He is a person of great courage, yet he is afraid of silly things like ghosts. I can replace yet in this context with "at the same time".

He is a person of great courage, at the same time he is afraid of silly things like ghosts. But in this case the meaning a little skewed.

There's got to be an entirely different way to put together the sentence.

Maybe like this.

Except for his silly fear of ghosts, he is an exceptionally brave man.

Come to think of it in the sentence in question I can entirely remove 'yet'.

In cases like these, Vera had an expert eye. She could easily peak out the difference between Guangzhou and Milan.

he has an athletic built or is athletically built

I sense the difference but cannot pick out which construct is more correct. To me, these constructs are semantically interchangeable, and their usage depends on the word order of the surrounding phrase. But I might be wrong. )
