Lis's Viking Thumbs

So I think I have a pretty clear idea of where I'm going with this, I just need help deciding on the composition that works best... It's kind of a wrap-around book cover size (but it doesn't necessarily have to be composed like a book cover)... but I don't know if I want the goddess turning her face toward the ship, or away from them with her eyes turned toward the ship, or if I want her flipped in the other direction! :P

Anyway, Rán is a Norse sea goddess and she likes to drown sailors (http://en.wikipedia.org/wiki/Rán), so I have a viking ship in stormy seas struggling to stay upright and get to shore (or just away!), and Rán is rising from the sea. I'm pretty exciting about painting this!!!!

I envision Rán to have multiple 'tiers' - her bottom half is foamy with waves and water splashing (water spout-like), and she still has some hair dragging in the sea, but in the middle her body becomes less water and more of just a transparent-ish being, and at top i want the rest of her hair to be flying around and kind of blending in with the clouds. In the foreground the ship/sea will be the darkest with bolder outlines, and there should be a nice atmospheric gradient to the distance. I also want there to be lights visible on the shore from torches/huts. Oh... and she'll be wearing some clothes... though one boob might be hanging out.... goddess style.
