Cropping / framing the picture is the most impactful instrument. In this case I would crop unnecessary information (noise) out of the photo:
- reduce amount of the sky,
- cut from below to keep building nicely aligned in lower 2/3,
- remove a bit from the left so that the car is not pooling attention and to reduce green colour.
Picture will completely shift it's attention and mood.
Sometimes I even make few different framings as copies and get more than one story.
I read it and was trying to understand why Death suddenly speaks German on 3rd panel xD
