The lighting is based on target direct light, VRay light and HDRI.
Note: the target direct light parallel with VRay light 1 because I need one shadow from the window, target direct light for sunlight affect, Vray light 1 for specular, Vray light 2 more lighting without specular, HDRI for affect diffuse and specular.
These are the lighting settings used in this image
