Impa, Impa, and Impa

This is a drawing of Impa, Impa, and hey…-Impa!
I know that the characters for the Zelda series look different sometimes, (and sometimes not even the same person, just with the same name) but the difference with Impa shocked me.
From left to right (Same with more recent-older)

Impa from Ocarina of Time, Impa from the Oracle series, and Impa from The Legend of Zelda

I personally prefer Impa from OoT, but I think that’s because I’m more used to her. (I never really seen the other designs of Impa before till recently, I think I have seen The Legend of Zelda years ago, but not the Oracle series one.)

Which design do you guys prefer and why?

(I think it turned out well for never drawing any of the Impa's before.)
