Mermaid's lower body type - With butt shape(no scale in butt)

this shape is another version of butt shape mermaids.
and my favorite mermaid charactor type.
why i draw this mermaid type, When mermaid sit on a rock, butt is rubbed on the rocks, and scales in butt is fall off. so, i think this shape is a comfortable body structure for semiaquatic style. (especially in the sitting position.)


※ I talk about mermaid’s fish body type. so, don’t talk about her fins and gills type this part.
※ I'm sorry, but my english language speech is very not good well. so, maybe discomfortable to reading my explain.
please look at the context and understand yourself.
thank you.
