Window Key
The window is your only source. Stand the subject at ~45° to the glass and a little below its center so the light rakes down across the face and carves the triangle on the far cheek.

Key notes

1Turn the face slowly toward the window until a small triangle of light appears on the shadow cheek, under the far eye — that is the Rembrandt.
2Diffuse harsh sun with a sheer curtain or frost; soft overcast "open shade" light needs no diffusion at all.
3Let the shadow side stay dark for mood — add a white bounce camera-left only if the shadow-side eye goes fully black.
4Move the subject closer to the glass for softer light with faster falloff; farther away for flatter, more even light.
