That’s some exotic fish of a merman! (http://www.pxleyes.com/blog/2013/01/exotic-fish-underwater-photography/ 😉 😛 ).
I would have expected bluish colors all over, but the contrast between the oranges and blue hues of the water look definitely amazing! Great composition and great result all over. 🙂
In my opinion, the blur on the second one looks very fine in the water but it muddies the character. It would be nice if you could separate the two effects : keeping the character intact and still applying some blur effect on the water 🙂
