The delivery of this character portrays stereotypical cartoon characteristics of "femme" body representation--so you're not bad at drawing girls! This character you made does tell me she is perhaps a love interest--as she has a sweet/kind face and is wearing cute tight attire. If that is what you are trying to convey, then you nailed it!
(But seriously, do not worry about representational gender as the point of reference for "accurate" body type. Learning anatomy and proportion should be just about that--anatomy and proportion. Some female people have totally flat chests and straight hips, some male people have very rounded hips with big chests. With character design in mind, and with stylization, it is up to YOU the artist to put those details in to convey what you'd like.)
Don't sweat it!
