Dark Nami Skin
The top is the original and the bottom one of course is a work in progress. A dark thunder Nami. I am still working on adding in the shading details to the fins which will be the dark teal. I am also working on changing her staff into a trident. I have yet to start working on the animation aspects of her spells though of course these would also change. Her Q would be a swirl of marbled dark teal and royal purple. Her W would splash dark purple and slate black. Her E would encase the target in two purple and one teal bubble along with black crackling lighting. Her R would color into mostely slate black with tendrils of purple and teal. Not really sure what more to put here so, I hope you like the concept and if you have anything to add please feel free to comment.
