- The lighting is uniformly flat. Often, I have found what is happening off frame is just as important as what's going on in frame.
- There is nothing in any of the reflections to hint at the surroundings to drive interest. (see above)
- The models that you made for the stands are incredibly blocky. Think about use cases of how they would be used if they were used for real (your cup dispenser would be unusable & it would be incredibly awkward grabbing pastries, etc)
- There is no human element to the placement of any of the treats, ie) they are so uniform spaced and placed that it looks artificial.
- The texturing is kinda lazy, the UVs for your the wood shelves have little consistency or logic behind them. Everything is too clean, there should be wear& dirt from use (again human element).
- your tonemapping looks kinda weird, not sure what's going on there.
Hope this helps!
