Again, the colors and values are very pleasing. Beyond that, much depends on your choices. For example, there's a hard edged quality to your brush strokes. My most satisfactory work has been where there's a lot of seamless-ness. So I'm more familiar with that approach. Where that works for me is both in the actual blending of paint as well as mixing more gradient steps within a color and between colors. But then it becomes a matter of feel where it should go one way or another. The color variation where you have multiple values of turquoise in the cresting wave is luminous and quite nice. The variation makes it interesting to look at. Conversely, where some of the areas go from darker turquoise to white, it creates a contrast that is a little jarring to my eye.
Overall, I'm liking your work. If you're going for a calligraphic look, then I would suggest more control with your "calligraphy", where it demonstrates a mastery of the brush and a deliberateness of design. But you might want to think about exploring where you want to place your marks and what about those marks would make it exciting and artful, like a master swordsman controls his rapier. You're getting closer. Those are just a few thoughts for your consideration. But nice work. It's a pleasing painting.
