He has an phenomenal grasp of color and composition, even when its not just a close-up portrait. His India work has tons to learn from.
Small list of compositional techniques he broadly imposes on his images:
1. Chiascoro lighting
2. Depth lighting
3. Natural framing (to tell a larger story)
4. Color cohesion/consistency
5. Areas of Greatest Contrast
6. Deep depth/balance
7. Rule of Odds/Asymmetrical compositions
He has so much to offer a photographer. You could basically learn everything you need to know to take a good photo by studying his works.
