Zubeir you should also put Masai in there as well as Samburu.
the Samburu in particular have that classic Somali appearance that is hard to reproduce by just mixing bantus with whites. tall, dark skin, slender, with a narrow nose and meduim thick lips. really the only difference i can see most times between the samburu and somali is that we have more people with timo jileec while they are almost exclusively jareer. other than that, there is little to no difference in facial features or build.
none of these light skin mulatoos pictured here resemble the classic somali figure.
