Bloom in Autumn

There is a 300 meter drop off next to the road. Is that evident in the image? How might

it be improved? Less foreground more cliff?

Wow, it is hard to say 300 meters, but it is obviously a great drop (more evident at the end of the canyon). You could improve the picture taking it later, when the lower sun light (I assume it is an afternoon picture) enhances the volume of the cliffs. I like composition (I'm unsure how you could improve this, maybe placing the bush more at right?) and especially color.
