A painting has no effect on Feng Shui. If you must use feng shui analysis, then analyze it according to the color of the painting. For example, the lotus leaf is very green and belongs to strong wood. If the owner needs wood, that would be great!
But this has no effect on feng shui, don't worry! It is the things that can be seen and touched that have a great feng shui effect. For example, a table has a greater effect than this picture.
