I don't know what it is with mermaids- I constantly draw/paint them.
You know those times when you have the itch to draw something, and you have this blank canvas in front of you, but nothing comes to mind?
My default is mermaid, it always happens!
My grandmother always said that the Irish were descended from dolphins and that our family especially was still strongly related to those ancestors. Mostly because some of us have webbed toes (she and my brother) hahaha.
