All of the bases have the problem of a head that is looking down in traditional 3/4ths and the bodies on a flat plane parallel to us.
The easy ( partial fix) is making the legs proportionately shorter.
The palette of the right is much more naturalistic and successful than either of the other iterations.
"supergamma filtered paletted game with pinks and blues so bright they could burn through the hemisphere. No professional Pixel Artist will tell you that the base all the way on the right is even CONSIDERABLE, given all the anatomical incorrections it has."
This is a gross exaggeration, to the point of being untrue on both accounts: the palette is relatively normal in terms of saturation, and any professional pixel artist would easily prefer the bases on the right to the other; yes some of the anatomy isn't perfect, but it's forgivable by means of style and time restrictions.
