I'm afraid my advice is unpleasant, make her 25% the size you have her now
oh, and come up with more interesting fairy garb, she's quite ordinary. and where's that flowing ethereal fairy hairstyle at? she's balding horribly, it's disgraceful
she's magical, make that tooth float and glow and stuff. why is it so huge? is it like an ad or something symbolic?
anat proportions are way off. measure the segments of her arms and legs and compare them - just drag out a nondestructible vector line parallel with each segment and then rotate them and fit them to the other side of her body, account for a little perspective diminish, but not much - if any
no wings?
no sparkly magic looking pixy dust floating around maybe even indicating her trail of movement?
give her a little waist purse thingy that implies she has coinage to leave when she gets a tooth
that facial expression is rather not exciting, give her a nice pretty smile
snap snap, make it happen, we dont got time to fool around!
