UE4 Environment | "The Pale Elk"

For this piece I really wanted to emphasize mood, lighting and atmosphere, along with getting as much motion into the scene as I could. The idea is that the 'green flash' which occurs at sunset and sunrise is actually a portal, taking one to this realm where shipwrecks and odd physics await. I wanted to leave a little mystery as to what actually happened/happens here: did The Pale Elk destroy all these other ships which float by, or is it simply the next victim?
