This here is the initial sketch
First I drew back the lines to get them connected and make it easier to use the wand tool.
To do stuff like this.
Next I wanted to make a more memorable sky so I selected the whole blue sky with the wand tool and layered it.
Then I placed a very vividly coloured sky on top of the art piece.
And adjusted the layer arrangements. However I felt that the bright red colours on the right were contradictory to what was happening to the burning car in the middle so,
And flipped it horizontally. However, seeing that the two layers were not connected in the middle, I merged them,
And then I used the blending options to adjust the opacity as to not outshine the foreground.
As for the bottom half of the art piece, I had to deviate from my original sketch because I was unable to make it happen the way I would have liked. So I inserted an image of a red line.
And that would be meant to be as the flow of blood but it did not show two contrasting sides as the upper half of the art piece did so
Thus, here is my final design.
