If I had to pick anyone from this list, kind of Mulan. I don't really know, Tiana's kind of her own indepentdant person. Love her ♥♥

Belle, only with a lot more attitude and definitely not with her head in the clouds so much. *sigh* I wish she was a dreamer...sort of like jasmine, but not as flirty and definitely not as snarky...okay, so not really like jasmine.

or mulan

Belle or Cinderella. Cinderella believes in working hard too. Ariel also works pretty hard to get what she wants. But Tiana is much more grounded than all of them.

Totally Belle, with a mixture of Ariel. :P
She works hard and has an acual dream that she wants just like Ariel, but KNOWS what to do to get there, and is witty and smart like Belle.
My two favorite Princesses mixed into one. <3

Oh, and how can she be 'flirty' like Jasmine when Naveen is the flirty one? =P

hmmm, actually, now maybe i would choose mulan...

Because they are independant and kills of their villain in the end of the movie (Tiana destroyed the necklace that Dr. Facilier had and his friends killed him)! Belle is also very similar which is weird because Belle is my 3rd favorite and Tiana is my 7th!
