"He saw her face above himself."

Translation: Viděl nad sebou její obličej.

What about "tvař"? Can we use it here?

[endless_sleeper]

tvář

[dude_in_sky]

Yes, but lost diacritics usually do not count as errors. So, can we use it?

[nueby]

You can use it, but if you don't care about the diacritics, stick with "oblicej" to avoid ambiguity.
