Abyssal Sadness [Request]

Well then... The idea was a water warrior. A spirit of the sadness and the loneliness, so she is ever sad. Plus, she's half human and half sea serpent. All the design and details have been previously discussed (literally everything haha)

This was the first time that I tried to draw some things, like the bubbles (great for a first try).
And I still need to improve the hair highlights, I'm having some trouble to learn how to do it properly :/

Hope u like my work! ^^
