Here is the thing: the foreground of this type should not be uniformly dark or light, it should gradually move from dark to light(er), i.e., the closest foreground the darkest. That way you are leading the viewer toward the main point of interest.
You also might want to consider what to do with the figure there, which wasn't visible in the OP. To clone it out or, if to leave, to lighten it enough to differentiate from the rest?
