She's very cute. I really love the soft coloring--especially in her hair, the lavendar-ish pink and yellow go really well together, surprisingly. I like her slightly droopy eyes--they make her look sleepy in a cute kind of way. The little star and moon on her cheek and her jewelry are really great touches--they make her seem like a dreamy kind of character. And I love the name Tropicana--it really suits her. :) I'm guessing most of the 'blockiness' in the lines is caused by transfer to .jpg? If not, that would be the only thing I would suggest--running a 'noise reduction tool' like the ones Adobe programs have, to make the image less blocky.
