Well done..... very realistic and yet whimsical. The water and clouds look real but still don't take away from the subject. The body and fish shapes and detail are very good and realistic as well as the textures. The shading on the angles and curves are good giving her the curviture she needs. The face is cute especially with the eyes looking upwared. It looks freehand which is hard to do. I think it should sell well and would make a great poster for people who like this kind of art. For the style you're working in, it's just right.
