Indeed you did a lovely job with the build anatomy. I absolutely love it! Other than, if you want to get liquid based matter correct, you'd have to definitely study from references. The sand might be too yellow as well. There's obvious sunlight, so we should be able to see some small white reflections on the water that's closer to us. And naturally, the distant water over at the horizon would be a darker hue than the rest of the water's coloration even when there's strong sunlight. We also would not see any refraction at the horizon. All this would bring your oceans to be more natural. Overall, this shark lady is the spotlight here, so nothing to worry about. Lover her! <3
