I wouldnt call it realistic since I have yet to see a human like that. It looks more like an orc and a nord got a baby witch turned out to be white instead of green. Eye's look weird without detail and they are oversized. Im not scouting a nose witch would be one of the key elements to realistic, just as some ears. I'm going to asume this is a wip and say its a good wip for a white orc. Yet if it isn't, I dont know what to say.
Keep it up.
