Hey the latest 3 photos looks much better.
Well maybe it is just my point of view. Normally just referring to evaluation of food itself, in chinese there is often used term Se Xiang Wei Ju Quan aka Color Fragrance Taste, all these 3 factors are present. Color is a vital factor of a person's first impression. So if the color is good, it makes the food looks tasty.
Having even a slight warm orangery color tone overpowering the real color take away a part of the food impression and reduces the overall contrast of the photo. With the correct color and vibrancy, it makes the food looks much more inviting (the latest 3 photos have this factor).
