Help with quality issues rejections

[OK82]

I've been uploading to Adobe stock for about a year now with most of my images being approved usually.
Recently Adobe has started to reject almost all of my images for quality issues. I've been trying to re-edit the photos and figure out what those quality issues might be, but I've ran out of ideas.

Here are few examples of latest rejected photos if you can help me out pointing what's wrong with them?

In the first image the spider is not in sharp focus, which becomes evident when you zoom in and inspect carefully.

same issue with the second image; the plant is not in sharp focus and there's a bit of chromatic aberration 

in the third image, when zoomed in, the grains in the bowls are perhaps not sharply focused enough.

Hi @OK82 ,

The first file's subject is too small and out of focus. It probably would be more interesting if there was some action in the sky, like some clouds. Also the file has a white balance issue.

The second file's subject is too small. Too much negative space. Details are lost in the highlights and there is a small amount of blue on the edges especially in the highlights.

The third is the best of all three files. That too has a white balance issue and is underexposed. The photo has a blue cast.

Best wishes
