You can only see this eight-character from here. Fire is stronger, water is weaker, and soil and gold are scarce.
If your constellation needs five elements of earth or five elements of gold, I think it is ok, because your fire is very strong and you need to vent. Fire produces soil, fire is like gold, and soil gold can vent fire. It should be enough to make up for these two things.
However, because I don't know the yen, it's all speculation.
I suggest you find a master who is good at balancing the five elements, help you have a look, and design a solution for you.
As far as I know, there is a master named Ayu who is good at this. He used to be a sculptor, making some Feng Shui eight-character sculptures for everyone. However, he knows the five elements of Zhouyi very well, so it is not a problem to design this balance plan for you. He also has a Taobao shop, which is friendly. Tell him well, he will definitely give you a good plan, you have it with him, and then ask him to make one for you.
