The photos you shared are interesting and very artistic, but they are the work of others. In fact, you shared too many photos, so you couldn’t describe them in detail. Please note that sharing too many photos without providing detailed explanations makes the post less engaging.

You didn't mention in the contest that I can not share the work of others and I captioned every photos. I shared more than 6-8 photos but got less mark which is disappointing.I don't know what kind of details are you asking, are you asking to write a paragraph under every photo? It is noticeable that you are giving more mark to the participants who didn't share quality image.
