Here's my take on this set. There are two strong light sources. One from the left and one from the right. This is illustrated in the 2nd photo by looking at the lamp shade itself. It's lit on both the left and right edge. The left source is not lighting the person's face and is likely the sun. The right is likely a bounce from the sun (shiny board, or soft bounce or wall) or an large HMI. The right source is very close to the window. The reason you have no v blind pattern on her face is the source from the right is too soft to create the pattern on the face; yet it IS creating a pattern on the window curtain. The pattern on the curtain is because the curtain is much closer to the blinds than the face. Generally, soft light doesn't make patterns, yet even soft light will create patterns if the gobo is relatively close to the subject where the pattern would display itself. Kapeesh?
