I really like the colors so far! I think that the composition might be stronger if you make it so that her head isn’t in the center of the image, since that usually tends to stiffen up the composition. Try using the rule of thirds
Also, it really helps the composition when there is a path leading to the focal point. To do this, I would redraw the cloth on the right in a way that it would make a winding path that points towards her face; for example, it would start in the foreground, and then drag through the water, perhaps zig-zagging a bit to emphasize the scene’s depth, and then point up towards her face.
Lastly, the water texture and strokes can also be used to help convey depth in the piece. If the water strokes are larger closer towards the viewer and smaller as they reach the background, it will really help to enhance the depth.
I think it’s really coming along well, and I seriously am in love with the face design! Can’t wait to see it done
