I agree the symmetry between legs and head doesn't bode well. There's a kind of optical illusion involved which requires larger legs.
Your first draft from my edit is quite good, all it likely requires is thinning the legs slightly by cutting from the crotch (the red dot indicates this) and the neck bulge removed as you did for the second draft.
Please move the hands with whole upper part about 10 pix down, changing all the 8 angles involved with hand attachment to sharp edges.
Sorry for tossing around different ways, but we'll be better off making it satisfactory from the beginning.
Just pasting these for comparison here to see how badly the legs are changed actually to worse if vertical symmetry is required.
