His chin shpuld be near his throat apple.
He indeed look a tiny Weeny girafe necked.

The body has actually the same proportions as MOS body.
He is not smaller at all, hes actually beefier.
But he has short feet pegs, so no need to use the stand just give him longer MOS feet pegs.
Look at the gap between the top of the boots and the knees, bigger gap in mos, longer pegs.

Using the MOS head on this body showed that the proportions were the same.
