She looks beautiful!! I have to admit, that you are one of the most talented Princess Rosalina artists on the whole dA. You somehow capture her official look very well. The eye looks just like an official one. And it's shaded the same way, too
There's some mistakes, though. The right heel on her shoe is too short. The color you chose for her tounge doesn't blend naturally with her lip color and catches too much attention. her hands are not the right size at all compared to the rest of her body.
awww Rosie looks so pretty! you always draw her so well! X3 yay for goomba! better than my first one (i put his teeth on the wrong way round ) ohmygosh that eye! looks totally stunning!! i think the only critique i could give is the crown, it's drawn well but it's placed funny. then again, you could always say she placed it on her head really quickly without thinking about it x)
