I like them, but some of them look like she's got buck teeth ;-) Also could you make a few designs with her reading her book? There must be a reason why she isn't noticing him!
Actually, all of them have buck teeth! I really like the t-shirt and skirt combo (the last one), maybe give her a burnt orange shirt with Yoshi on it and a dark green skirt so that her colours sit well with the environment, to underline that she belongs to this world and Twit doesn't?
Haha, that was a lip highlight, will be sure to watch out for that next time.
