Hello Jaquilline! I loved your drawing so just wanted to give some feedback c: When do mermaid tails, I imagine that the range of motion at the hip is still limited just like a humans would be. I choose to do the same at the knee too, but afterwards i think it could be free reign to make some different shapes. Also I think adding some self-overlaps help to create depth too! I hope this helps c: | Artwod Feedback
