I like to play tall characters, so the first thing I did was crank up the height to 220cm. When I started adjusting weight, it just doesn't look right. At 220cm, a 154 kilo man simply does not look that big, especially a strong one. Perhaps base weight should be modified based on height.
I played with skin as well, and found that skin melanin below about 40 seems a bit off. Even very dark people don't look like a cardboard cutout of a starless night. Certain parts of the body are always lighter. Hands, etc. The fact that the loinpiece also changes color probably helps make this more annoying
