You wrote at the bottom this was still in progress, but what part is? Is the coloring additons the progress? Because this is in serious need of coloring but if you plan to keep it black and white then work on the exposure elements of the whites as they all seem too grey and are getting lost inside with the blacks and shades. I love the design of the mermaid type girl and the circle border background behind her. I think that alone is good work, but the coloring and shading do need to be improved on.
~~THINGS TO IMPROVE ON~~
As stated above, just work on coloring and shading as you progress.
