I like the shadow treatment author.

Nice idea, but the light on the waves is opposite the light on her face, and the tail looks 20 feet long.

CMYK46 you are right on all the points, i cannot denied ! but i was sure something went wrong with my pics .)

The tail looks like its a airport landing strip

hard work, some burn shadow beneath her might help, very good idea, and good luck

Try using the warp tool on the tail to create a more rounded look. Good luck)

you can still fix the tail with the liquify filter

I think you need to work on your equalization... look at the whole image and think it should blend... good luck, but work more.. but as always Just IMHO
