Beta themed Nami Skin (Artwork included & more comming!)

So I have been trying to think of a way to do a kool dark looking skin for Nami without going for the obvious "evil skin". Plus I'm sure the riot team has a deep sea skin or something of the sort already in the works for her so this was the idea I came up with. I work in a pet shop and have been looking at all the beta fish we get in and all the different colors and it hit me. Why not do the almost pure black beta with the fluorescent blues and greens as something to break it up. Her face chest, underarms etc. would be the black with the dark olive green undertones and highlights, then she would have highlights on her scales and in her fins of the blue's and greens.

Now ill be adding basic color pallets later of the other color options I really like as well such as, a pale gold with highlights of pink and red as well as purple most likely. Or vibrant reds, maybe even with dark blues. Or purples and blues. There are endless options so post ones you think would look great as well, and let me know what you think of this!
