Why was this photo was declined?

The 2 handles in the window don't make sense:

Your first is too small to ckeck correctly. The histogram shows missing blacks. That is an exposure issue and would qualify as quality error.

Your second is conceptually unrealistic, besides the rendering errors. You do not hold an orange like that to squeeze it, your fingers have texture errors, there is an outline between the hand and the background. To get a flow that makes the fluid swap over like this, you would need to use a different system. In any case, the juice rinsal is not enough.. And getting this flow coming out of an unsqueezed orange is unrealistic too. 

Your campfire is also full of conceptual errors. I couldn't use this for any adventurous camping advert. But there are also rendering errors present: 

Conceptual errors: tent placement, firewood, cooking tripod (you won't take such a tripod with you), you do not take wool covers on a trekking tour, etc.

And just to be extra picky, these are not photos but AI. 😉
