The overall MOC is nice, don't get me wrong, you did use all the right parts in all the right places. Thing that sticks out to me, in a surprisingly good way is the waist, as it reminded me of those stylised stick thin female cartoons I saw back in the day. Love it!
The custom body is appreciated, and the combination of yellows makes an adequate color scheme. I would, however, suggest bulking the area of her head between the white piece (visor?) and the hair attachment. A less rigid, more detailed torso would also be appreciated; likewise the legs would benefit from more greebling and the arms too seems rather spindly. I saw this was already mentioned on one of your mocs, but I would repeat that larger pictures would enhance your mocs. Keep working at it!
