Just a bit too filter heavy for my taste, but I see where you're coming from...GL author.

If the writing is your name (watermark) then it must be removed as per the Rules & Guidelines.

"Less is more" applies not only to images but to titles and descriptions as well. While a gyotaku may have inspired you, it was TMI [too much information] that distracted from rather than adding to my appreciation of your entry. I would just delete the references to gyotaku.

I don't know anything about gyotaku, but I would hang a print of this up in my living room.

The watercolor aspect is obvious with an unusually somber (not pastel!) color palette that makes the image unique. But I don't really see the gyotaku which apparently is just a largely monochromatic rubbing of the fish's surface to yield a pretty flat kind of superficial X-ray of the fish (I'm reminded of fossils) without the addition of any other elements (such as seaweed, for example).
