Hello everyone, the picture itself is abit confusing since you need to know the story behind it to really understand whats going on here, so let me explain.

Its basicly a "fighting scene" between Sasuke and Naruto, you can see Sasukes feets in the top right corner and Sasuke is wounded by Naruto so hes bleeding quite alot.

Naruto have just been punched down in water and been wounded at several places, you can also see hes cut-wounds on hes cheeks, also Red chakra is coming out from naruto bubbling underneath the water, so yeh its not blood and you can also see Naruto getting hes arm above the watersurface hoping for Sasuke to change hes mind and help Naruto.

This picture is Done with:
Wacom tablet
mouse
Photoshop cs2
Referense: my hand only, else I didnt use any referense
Inspiration: One piece (the sea and sharks), sasuke vs naruto fight in the manga/anime
Orginal size 1700x1700 pixels

Updated!
This was the intended version of it from the beginning, removed the shark and added the knife with the explosion tag on it, its abit small but it was about two years ago I did it, and I cant be arsed fixit it now, if anything I would make a whole new remake of this one.

Also changed the color adjustment, its more dark and more serious feeling over it.
