Thank you @me422us for taking time to provide such a detailed explanation, it's really appreciated. This journey has been one of learning and I am thankful that you bought this to me attention. For me, a mermaid is a mythical creature and therefore it's anatomy is for each of us to imagine and create.

I will look further into what you have said and take it into consideration when working on my future sculptures. It would be great to get your view on it
