Well if you choose medium skin you opt in to less realism in my opinion. You can´t show a hairline and is forced to cover it up keeping it dense to hide away the skin (0,1mm) combined with your choosing of a spiky upwards front. You hair looks silver colored, but I guess it´s the light playing a trick or perhaps you´ve choosen synthetic hair - it dosen´t look gray (but silver). If you´r happy that´s all that matters really.
