Fiction Adaptation - Graphic Ideas

For my film I have loads of good ideas for the graphics.

For the first scene where I want graphics is the stabbing scene, this is when David get stabbed, I want to have every time it goes to a POV shot of David, I want it in all in black and white. This i think will add to the illusion that he is not well and hurt and doesn't fit in the scene.

I want it to look like this;

I want the effect to happen when David is looking at his friend, his eyes will look down at his poppy and the poppy will be i colour. This will be a nice contrast for the shot and add to the film.

The second bit of graphic I want is the Clouds part, this is where David has passed out and looking up and above him clouds, stars and colours pass by, tho will tie in nicely with the poem and it mentions passing clouds and stars. Also I want to show that he is passing on in the film, so this will add to the story line also.

I want it to look like this:

The final scene in which I want the use of graphics is when David see a TV in the forest, I want the TV to show all static effects, then cut to a TV shot of the flash back before cutting to the flash back. 

This is to make the scene understanding of a flash back, so that the viewers know. Also with the trippy effects I think it'll definitely add to the scene.

Something like this:
