I start with the idea to make a Nereide water spirit and it evolved on a Scylla Sea witch who can manipulate water for make defensive shields , throw water bullets and slice enemyes with high pressure water cutters, also she have a little cute crab pet as compagnion and can command giant abyssal crabs on war for defend her Sea
Here some initial sketch idea

aww! cute
I really like the retro anime style you have going on in the large bust. It gives me leiji matsumoto vibes
I also think the design overall would benefit from a much more simplified way of defining the chest. Its like, they're both nearly perfect circles so it creates an odd focal point @_@. I'd merely just keep the silhouette and erase the delineation between them

haha you are right, now that i see later the hair reming me Masha from galaxy express 999
