lighting clashes between the skeleton, tower and sand. The shadow the fish is casting is also incorrect. I'm not too sure what that spike is beneath the fish either... you should upload a high res version so it can be seen better.

its surealism ponti , the fish is not casting any shadow, the grain and the overall color composition for me is the title "nightmare fishing" , i apreciate your comment.

i love surealism images some of my favourites are ones with shadows, they just dont match the object they come from ;p maybe give that a go too...

Surrealistic or not, lighting is a basic principle in all images... it may never be 100% right but something as simple as flipping the tower would improve your image. If you'd like to go into more depth then i also suggest trying to make the strong dark shadow from the original source much softer and brighter to fit in with the surroundings. (look at how soft the shadows on the sand are)

um, not bad

cool idea....gl
