I am surprised Mosh would let this photo be published. Bad posture and no fake "I am happy smile". This picture shows a very unhappy woman.
The photo masks all her flaws: The angle hide her wonky right eye. The too bright white light washes out all the lines and wrinkles on her skin. The side view also makes her look more slender. Adding Photoshop, viola! I bet she likes it. She looks like a QUEEN. That's all that matters.
Plus, at that time, the gown had a better fit around the bust/waist AND she had better tiara hair, instead of the Crocker Spaniel she sported two days ago AND the overall appearance is better with the parure necklace only plus the sash, compared to brooch with elephant chain.
Although she looks kinda depressed in the pic, the overall pic composition, especially background color echoing sash color, is very good.
Pity that making her look good takes ages and is only possible in completely staged pics PLUS photoshop work afterwards.
