Conventional design but I admire your choosing of starfish as breast coverings for the mermaid rather than seashells. On that note, every seashell is the picture is stunningly detailed- impressive skill being displayed.
What really has me staring at this picture though, Maroon's beautifully serene expression.
Out of curiosity, did you use a real fish as a reference model for her scales and fins?
And for the record, I think "Maroon" is a much more fitting name for her. ("Mar" being a reference to what is the word for "sea" in many languages, or was that not intended?)
