To add to ​@yamato713108855 ‘s response about the mushrooms in the basket: the highlight at the given position is disturbing. You should aim for a more even lightning. I agree with him on all other points.

The mushrooms in the basket are a matter of composition.
There is too much empty space at the bottom of the basket, and the top is cut off.

The second mushroom photo is too shallow in focus.

The pigeon isn't in focus in the photo.
The patchy lighting is also bothersome.

In the photo of the bee, the bee is not in focus.

The main issue I see is poor focus. Your depth of field could be better. Read your Contributor User Guide. It contains important information about what’s expected. Start with this 4-part Photography section.
