swallowed by the sea

Fantastic Shot - truly, not only does it look awesome, it must have taken tremendous time and effort to have captured.

I've only a few points to make in terms of areas of improvement...
- Color Scheme: Blue, with allowance of skin browns; given this, the black swimsuit is an unnecessary distraction - for the future, consider changing color during post work, or pick a a color that complements, instead of distracts - perhaps a dark green would have been suitable (especially if it matched somewhat the shadows in the water);
- Composition: fairly centered, with suggested focus on the shell spray of water; however, that is now what the eye is attracted to. You've used day lighting - giving us perfect detail of the female figure, even her expression - therefore, she is more of a subject than a collection of lines that complete the water arc. Also, the sea horizon line is fairly high - even though such plethora of the sea scape gives a richness of color, texture and waves - it overpowers with its vividness the bottom part of the spray arc. Both of the above mean that the spray doesn't get as much attention as it's center position would suggest.
- Feel: although the title suggest an act of submersion, she is actually plunging into the air; this action would be emphasized by a lower water horizon line;

So perhaps a suggestion for future posing - I wish there was much more water between the viewer and the model; then her color would not dominate the photograph as much, and we'd be able to focus much more on the movement of the water both near her torso, and from her hair.
