My opinions.
Jasmine... She's absolutely beautiful, but I think she should look more Indian than this rendering
Aurora... okay, she's supposed to be 16 -- this looks like an adult playing at being a teenager
Pocahontas... Disney's version is older than the real Pocahontas, but she looks too old here. Again, she looks a little too European and I'd prefer more Native American features. She does look a bit like Tia Carrere (well, if you squint your eyes...)
Belle... What's with the attitude? Belle is intelligent and beautiful - in this artistic rendering she looks kind of worn out and looks like she's saying, "hurry and take the picture." I think she's pretty, but I like to look at 'pleasant' not 'irritated' princesses.
Esmerelda... drop dead gorgeous here. Looks more 'European' than 'gypsy' to me, though... but, yeah, if I were a guy, I'd probably want to meet her
Ariel... Looks like a cute, young mermaid. It's a nice rendition of her
Ursula... hilarious - yup, I wouldn't change this one
Megara... I think this is a good representation of what she would look like, with facial expression and all. Nicely done
Mulan... I think the artist did a good job with Mulan. She reminds me a bit of one of our DISers, Rochelle (eatmypixiedust)
There are a lot of good ones, but my favorites would be Esmeralda, Jasmine, and the Little Mermaid.
That was fun, Nancy
