We are split between the icon is #56 and #34.
Can you remove the "heads" from #56 and make the right side of the M or right person a little shorter, which will give it an italic look but represent one shorter person...probably the female. Since it will have an italic look maybe also try an italic version of the font. Even Adobe Caslon Pro in italic.
For #34 can you remove the two little marks at the bottom of the center of the M.
Thanks!
