IMHO you may want to smooth out the bottom jaw's tip (it's cut very hard, as are the tail tips) Blur and erase brushes may help to add to realism, SBS will help for higher votes... More help is surely on it's way

Very good job and good luck

Thank you, Drivenslush!

Why would there be drops of water on a fish underwater...???
(Blur sharp edges as said above).

It was deliberate, to show only the work removed from the original image, but your comment was very good, thank you, CMYK46!

It shouldn't be difficult to remove those drops.

The drops could just be fish warts. The lack of shadiing on the fish makes it seem overly flat. Also, the top and bottom (dorsal and anti-dorsal?) fins seem behind rather than connected to the fish.

very nice!

Thank you, DanLundberg and Derivatix !

congrats...
