honestly 你 do need to work on anatomy, arm length and legs. It's a great start though, 你 can only improve just remember that and keep practicing. 你 did a good job on the face and hair though ^^. Yes I would say 你 need to work on detail but I would worry about detail 更多 after perfecting the body shape, anatomy, etc. But yeah for just doodling it looks really good keep going! I like the hair, 你 did a good job on the bangs and adding detail to the bottom of the pig tails!
