I prefer
Ulyana but
Uliana is nice enough. I can see it as an alternative to the older Julia/Julie even though it itself is a variant.
It would be great on a sci-fi or fantasy character or in an historical piece.
Hbo recently used the name Ulana for Chernobyl on their composite scientist character to represent the many that were involved . (I had to look this up to be sure because I wasn't quite sure.)
It's not quite my style but potential combos:
Uliana ElisavetaUliana JuanitaUliana BlagunaUliana EvangelineUliana Sutton
Uliana PrudenceUliana IvanaUliana IsoldeUliana Isobel
