Or at least as complete as it's going to be. I'm really very happy with the new paw results, actually. I don't think there's anything else left to be done to improve it. Maybe a tweak here and there, but really they would be very difficult to notice.

Shape-wise, the final product is a vast improvement over the original. It's actually quite close to the mockup, but I hit upon the means to draw the base of the outer two digits much closer to the paw pad. The final product is much tighter for it. I managed to decrease the width without impacting the shape of the digits or foot too much.

The edgeloops remain the same, albeit shuffled about. When not smoothed, the digits actually overlap a bit. Getting the shape I wanted when smoothed require a lot of odd shape work in the unsmoothed part. But, the most noticible oddity was the skeleton it required. Look at that thing! I was hoping to come up with a better version, but was unsuccessful. As such, the paws require a handful of touch-ups with skin-weight painting, everytime I bind it. No amount of playing with the skeleton seems to resolve this. It's weird; some weight bindings jump to neighboring meshes, seemingly skipping over joints that ought to be closer...
