I going to go out on a limb and say not human There seems to be no eye lids but the eyes look good, and I like the texture of the skin, perhaps give your small recessed dots a different darker material with a new texture to make them there own. The mouth, even if it’s not a human head, could use a lot of work, more loops around the opening to give it a more gradual rounded look like lips ususally are. Looks like you made teeth so show them off a bit more, does it have a lower set as well? The ear nob is kind of strange. Over all though you have a great start, which I could give you some tips on particles for the hair, but I have yet to play with those myself. Keep it up!!
