I'm a relative newbie to pixel art, but don't let that hold you back. I've been working on this for a day or two and I'd like it to turn out well.
As you can see I've never been any good at water, there just seems to be some trick to it that no matter how much I study other works I simply don't get. I doubt the horizon should look like that. And it would be good if the rocks ceased to look like cloth. Just so you know, she's coming out of the rock. It might be too light, since my monitor is at maximum brightness/contrast and I still can't see very dark colours against one another.
I wasn't sure whether or not to give this a nudity tag. I decided to leave it off since she's... a rock. But I'm sure you'll let me know if I did so in error.
