Fantasy Art Anime style Mermaid Hero

The design, lineart and colors are all great! The glow effects are simple but efficient and the shadows are very clean. I think however the posing is the weakest part. It looks good composition-wise, but when you look at it it's hard to understand what she's doing. Is she striking a pose? Getting ready to attack something? Her face is also very neutral, which makes her intentions very vague. Her hands also don't seem to quite hold that trident and it feels like it'll just fall off of her hands. All in all though, very solid piece of work.
