Nami Skin ideas
Also posted it on reddit but here are my ideas. My first idea would be a halloween theme where nami is an angler fish because those guys are creepy looking. Also since some angler fish have lights to attract prey so you can have a light blink on nami when she uses a skill. The fish in her taunt can be angler fish.
My second idea is based on the little mermaid where Nami is human. You can have her splash art be her coming out of the water that way her in game animation can be her floating in water. Oh and she could be wearing tattered clothes and her trident can be gold or it could be a fork as a nod to the movie little mermaid of ariel using it to comb her hair. Aslo the fish in her animation can be overly cute looking fish. Her hair can be blonde with bits of blue in there.
