I've done the minor tweak you suggested, and it looks less like her joint swings backwards. Thanks again! :)

yep, i think your friend was right about the arm, the pose looks more dynamic if the arm is bending. You could try to flip the shading in the elbow, that might help :)

Thank you very much for taking the time to comment! Her free arm was actually pointing straight down in an earlier iteration, but a friend of mine told me that bending her elbow would look  "cooler".

I will try to rectify this when I have the time to do so. :)

nice dynamic stanse, but i would correct the elbow of the free hand, it seems like the arm is attached backwards in the joint
