Hi. The proportions are roughly ok (although the lower part of the body appears to be a bit too flat and small, especially compared to very thick legs; neck also could use a second look; back of the head might be a bit too big). The main problem I see is the gesture. The character seems to be falling down/float - which doesn't correspond to the relaxed gesture of the upper body. Try replicate this pose yourself in front of the mirror. I think it would work better if you made the character put some weight on the walking stick or assumed more stable standing pose. When in doubt, draw a rough construction over your drawing and check it out without all the details. You might see the issues that are buried under the lines.
Thanks, I've changed the way she's standing, and it looks better
