I confess: I let ?Heidi? both defy the natural law of gravity, so let her fly by her own will (not many ordinary girls do that you know!), but I could not stop there, I also gave her hair of steel!
To be honest I got very inspired by comic girl hairdos always look strange or even perfect (just like your own heroine's unrealistic hair), so try to do something similar. Sorry if I failed, I have to try harder next time!
