PERSONALITY

Petra's a soft spoken, caring, relaxed girl who values her personal relationships over everything else. She likes to keep her head up and stay positive, sometimes to a point where it seems like she's in her own world away from everyone else. She can also get clingy to the people she cares about, attaching herself so tightly that it can push people away with the intensity.

VOICE

Petra's voice is very distinct. A super high pitch, breathy soft voice, with a slight lisp. Petra speaks in long, unbroken sentences that can be tough to understand due to her breathy, soft voice. Other than taking in breaths after speaking too long, Petra rarely pauses when speaking. She's, overall, meant to sound a bit awkward and nerdy cute, which is what the lisp and mouth breathing voice is meant to channel. Petra never raises her voice, instead elongating the ends of sentences that would otherwise be shouted.

A voice reference for Petra would be Lily Allen, though more specifically her singing voice. She has a very soft way of singing that I think Petra would have even in her normal speaking voice (Of course, Petra won't be singing her lines so don't take this entirely). Lily also has a British accent which is very Petra.

Petra is from Britain, so a British accent would be huge bonus points but is not required.
