Worked on this character for ages, don't have much to say that isn't in the description.
In case it is not obvious, she is a trans filly. And by this point because Equestria likely has a wealth of options available, I find it hard to imagine she's not 100% female by now in all respects.

She likes learning the guitar and singing though she's a bit shy. She's studying in a college somewhere, not sure what she's studying, though often goes home to the equivalent of pony Ireland.
She comes across as passive and closed off, but she's very generous and selfless, very empathetic of others plights and needs and finds it hard not to try and support them.
