First of all, you have a wide range of topics, so you should avoid popularization when writing academic papers. The high prosperity of art in Song Dynasty is mainly reflected in university painting. Most of them wrote about flowers and birds in the Song Dynasty, the influence of university painting, Song Huizong and Evonne, and so on. There are too many people writing these articles, which are not fresh and practical. You know, many online searches have the same results.

Secondly, it seems that you didn't take China's art history and Chinese painting seriously, and your paper has no clue. Academic papers like art must be involved in their own (practical) experience in order to be vivid and true. Papers are usually the original crystallization of inspiration accumulated at ordinary times, but now they are difficult to suppress, and the result can be imagined.

I'll give you some easy topics to write:

Flowers and birds: the inspiration of sketching Zhao Chang (sketching is never out of date).

Right and wrong in Song Huizong and Evonne (there are many people who write this, so put forward new ideas, and be careful not to be identical)

Reflections on "Yellow is rich and Xu Xi is wild" (Study on the practicability and communication of painting)

Landscape: Fan Jiashan (landscape realism school in the Northern Song Dynasty), "Naturally, it was made by foreign teachers, and the heart came from China."

The influence of the four masters in the Southern Song Dynasty (Li, Liu, Ma and Xia) on the Zhejiang School in the Ming Dynasty (Dai Jin and Xia).

Wang Ximeng's A Thousand Miles of Mountains and Rivers (The practicability of green mountains and green waters: a discussion of small works or long volumes)
