She does feminine really well but I've always felt that she seems most comfortable when she's in tomboy mode. It seems to go better with her energetic, almost aggressive, style of dancing.
The only look I have a problem with is when she tries to be all kawaii and girly. Sometimes it works, like in the "Kissing you" PV but most of the time it feels overly forced like in the "Nanairo no Ashita" PV.
