Is the expression "yet from front, mediocre" okay?

Is that meant to be native English prose?

"yet from front" - means nothing to me.
It has the grammatical capacity to catch on ... but I'd never use it until I heard a thousands girls say it.
You would confuse a lot of people, but it works. I didn't know hat you were asking, until you provided a second example "when face to face."

In fact the entire sentence, is grammatically flawed in a lot of ways.

Viewpoints take a definite article ("the") - the front; the side; the rear (or the back).

I wonder whether the expression "yet from front, mediocre" is fine in English.

"Viewed from the side, I often find a stunning beauty; yet from the front, often mediocre."

In the green I italicized a grammatical error.

IN the first half of the statement, you are referring to a Beauty. Yet in the second statement there is no indication of such a thing. You must some how specify what is mediocre.
Although it is obvious, YOU are the beauty in the first statement made in the sentence, It does not say: that You (the allusive NOUN) looked mediocre; Or that you found "A mediocre prize/girl/figure/being/individual"


Beauty was used as a NOUN, Mediocre is not a noun, ever, it is an adjective.
"You are Mediocre" = adjective. "It was mediocre" = adjective. How mediocre was it?" = adjective.
