Here is my feedback on the new leg models introduced in Season 8. Although the new female calves look better with skirts and tight pants, the increased thickness of the thighs for tight pants makes them look unproportional in comparison to the calves. (Note that thighs for loose pants were made thicker as well.) Furthermore, the thighs for TOS skirts look thicker from the front and back than from the sides.
The female thighs for tight pants look overly muscular in comparison to the calves.
Similar problems can be seen with the new male thighs. The male thighs look too thick from the front and back, though they look all right from the sides. Notice how the quadriceps appear to bulge out when the character is viewed from the back.
Here "TOS skirt" means the TOS Split Skirt or TOS Nurse Skirt. The thighs for TOS skirts are thinner from the sides like the thighs for other skirts, but they are the thicker from the front and back like the thighs for tight pants and loose pants. The result is that the thighs for TOS skirts look thicker from the front and back than from the sides.
There is a range of opinions on this, and without getting myself too entrenched, I know frtoaster has been diligent about his analysis of the characters and wanted to clarify one aspect with the legs with skirts.
The legs with skirts unfortunately have to bee skinny from the sides so they don't clip with the skirts when walking, running, etc. They're about the same width from they side as they've always been, but from the front and back they now appear more natural.
