Sunita, maybe? Sounds more like a real name.
Sunshine here is a sort of endearment used by older men on girls - 'cheer up, sunshine'. It's the sort of name I can imagine
Jamie Oliver using.
Solana unfortunately reminds me of
Valerie Solanas (insane man-hater who tried to shoot
Andy Warhol). I like
Tesni and
Solveig.
