Im curious as to what you shoot with all the expensive equipment you have. Do you do product or model photography by any chance?
as for the image, you need to have a good eye and know about colors and what appeals to the eye. The shot could have potential with different crops and also the right color adjustments. you need to make the image "pop" by means of adjusting things such as lights, darks, highlights, shadows, saturation, luminance, etc...
you also have to think about how to place the foreground and how it would enhance the primary subject. I always am moving left and right up and down all while having the subject and foreground in my view, so that i can find the best angle to shoot. In this instance, it seems like the foreground is just protruding in to the image. You cant just pick out any foreground and assume itll accentuate depth and perception.
There are no rules for a good photograph and there are no excuses for a bad one.
