OK I did a little investigating. Unfortunately I no longer have the project file that I used to create that image.  

I do know for certain that I started with the Miki 4 head morph that you can find by selecting the head, and then going down to the Miki 4 Morphs section. Dial the Miki4 Head Morph to 1.  

Then I might have just played with the Eyes, Nose, and Mouth morphs to change it up a bit. For example, I might have used the UpperLidsUp and LowerLidsUp (this one set to negative) to make the eye shape look a little rounder, and the  LipsBig and BigBottom to plump up the lips a little. (None of these morphs are set to any higher than .5, I just tweaked them until I got a shape that was pleasing).

And then the texture is one of the "Asian Beauties" textures by Virtual_World that were originally created for Miki 3, but the textures also work on Miki 4 (lots of options there for eye color and makeups). They are available here in the Marketplace. I also applied snarly’s EZ Skin afterward.

The hair that I used was Fable Hair by As Shanim (now known as Aery Soul, but I looked here and at RDNA and it doesn't look like it is available any more ... one of my long time favorites).

Here's a quick render using just those morphs and extras that I described above. Add a slight smile and tweak the lighting and I think it comes real close to that character in the promo. The character in the middle may have been similar settings, but just a different selection from the Asian Beauties to change it up a little.

Miki 4 is still one of my favorite SM characters!
