As KickAir8p mentioned using subsurface might improve the skin.
Concerning the lighting, your model has a bright light above the head pointing downwards. Your reference seems to be lit from the front (a bit to the left) and only slightly raised. Most likely there's also some additional lighting.
When you want to figure out how an image is lit it helps to convert it to black and white. Then it is easier to see where shadows and highlight are. If you know where the shadows are (below the chin in this case) you can "reverse engineer" the position of the lamp(s).

This is how it turns out in Eevee:
And in Cycles:
I lit this scene with only three Arealamps:
