Something I've learned about shading on limbs is that it can serve (at least) two purposes. One is to show direction of light and areas of shadow. Another is to give a sense of depth.
In essence, both have the similar effect of creating the feeling of a 3D shape.
So in simple terms, a leg that's further away can just be made darker to give a sense of depth. But, also, the lower part of a leg that's nearer the viewer can be made darker to look like it's "tucked in" or bent back (and thus in shadow).
So this piece by Kenthecaptain shows the lower part of the legs bent back, giving a strong sense of 3D and emphasising the exaggerated 'hips thrust-forward' pose.
And after a quick scan through Twitter, here's an example of some characters with darker 'rear' legs:

The reason I mention this is that your recent version:
seems to do the opposite, if you see what I mean. The leg in front is darker, even though it's not bent back. The rear leg is bent back and lighter. This makes my brain interpret it as a very awkward twisted leg pose... But you know, that's just me.
