I don't understand your question. What do you consider a "non commercial photo"? All photos are required to meet the same quality standard in order to be accepted.
DSC_9286.jpg - these look delicious, but you've cropped in too close, cutting off part of the subject matter. Also slightly underexposed according to the histogram.
DSC_7888-Улучшено-NR.jpg - underexposed and depth of field is too shallow, resulting in much of the image being out of focus.
DSC_7637-Улучшено-NR.jpg - underexposed, cropped too close (or should have been shot in landscape orientation), many unfocused areas
DSC_7654-Exposure.jpg - there are some out of focus areas, probably due to depth of field being too shallow
DSC_7923-Улучшено-NR-Exposure.jpg - zoom in to 100-200% and you'll see that most of the purple flowers are not in focus; the sun flare might have been a problem too
