Half-assed edit, used some parts from other edits really quickly. Will finish later, got busy.

Really quickly though:
Use larger pixel clusters.
Check up on your anatomy.
Her height is fine, typical anime style lends itself to longer legs, this is fine.
Keep her hair to two colors if you are going to go that thin with the swirls, looks very messy as it is.
Calm down on trying to texture stuff. Usually no need at this resolution instead use shape, color, and large clusters to make details pop.
