And the picture ... needs some tightening up.
1 - Although her right leg is pretty good, the left is very stiff and not as fluid
2 - Her hips should be a bit wider for a female, I think
3 - That left arm of hers needs some re-working - it's too small and short in length
4 - her right arm ... is she muscular or not? If she isn't, the bicep may be slightly too large
5 - on that note, the way her right arm is bent looks like she's twisting her arm to hold the staff - very uncomfortable
6 - head needs to be a bit larger and centred on her shoulders
Also, from the pic itself, I get no indication of the emotion you said she portrays : rambunctious, enjoying fun - she seems to just be standing there doing nothing. Try to incorporate emotion in your work.
And also, invest in some unlined paper.
That is all.
