Please help me analyze this photo in detail from five angles: exposure, structure, light consumption, color and viewpoint! thank you

This is a macro photography with flowers as the theme. First of all, the first problem lies in the lens. Because the lens aperture is not large enough, the background is not blurred enough, and the subject is not prominent. A large number of messy backgrounds have strongly interfered with the subject. At the same time, composition is not very particular. If the aperture of the lens is not enough, this problem can also be solved by reasonable composition. It can be seen that the author didn't think much when shooting. In addition, the main body is not prominent in color (the background and the main body are the same color), regardless of the shape or color, the background can retreat and the main body can stand out. This is a failed work. It can be seen that there are few post-treatment methods. The composition is too full, and the picture is stuffy and lifeless. The semantics conveyed by the pictures are unclear, and the overall feeling is dull.
