Its pretty but needs resolution.
The beta is beautifully rendered and focused, but its almost too small of an area to hold the piece together. Its admirable to attempt a selective focus piece, but i think some of the clouds need a bit more definition in them. The fish shows you have skill, but the clouds make you look amatureish. Even keeping them blurry you can up their physical nature so that it shows that they are more than just white with a photoshop blur and smudge tool.
