Rainbow for Us

A sudden storm over the Santa Catalina Mountains near Tucson, Arizona.

What would you do differently?

J.W. I think if you took 1 or 2 steps to the left it would give you a better overall composition. Just enough to seperate the foreground tree from the background mountain and possibly push the rainbow a bit more towards the edge of the frame.

I agree - except that's the block wall and then there's an 8' stack of river boulders, so I just fired away!
