Here is my feedback on the new hand models introduced in Season 8. At first, I thought the new male hands looked too thick, but after examining the hands more carefully, I now think that the hand parts look too thick from certain angles and too thin from other angles. For example, compare the edge (above the pinkie) and the fingers of the right hand in the following screenshots.
In the second picture above, notice how the edge of the hand appears to drop straight down from the wrist with almost no curve. The thumbs also appear to have different thicknesses from different angles.
If possible, I would reduce the thickness of the hand parts along certain dimensions and increase them along other dimensions. Finally, the arms are shorter on both males and females, though it is much more noticeable on males.
