Same camera, different light, different results

Second painting continues on the Patroclus painting and I hope to finish it in the next few weeks. I'm considering the background and foreground done (except for the arrows in the front). Small areas still need to be rendered on the figure, particularly the hand, and the feet. Some edges need to be softened still (half-tones on the thigh and the upper shoulder. Finally, I'll redo the strands of hair...)

Two weeks ago, I took the pictures below at home, at virtually the same time, in different lights.
