Oh my gosh, where to begin? Between the overall tone of the piece, the delicate scale details on her arm, and all of the beautiful fishes around her, It makes me sad that this kind of thig does not exist in our world. Thank you for brightening my day, and congratulations on a well earned DD!
This is really pretty! I wish I could think of more to say, actually the details on the mermaid are really nice, half the time mermaid are drawn as literally half human half fish, without the blend you've got here!
