That looks a lot like mine, except mine is about half that long. Consider using cedar fence slats for the front and side and then stain them brown or black. Very natural looking and will last forever with no warping or buckling. Also, I've already had to repaint most of the plywood on the back of mine. The cedar is still dark black streaked with brown and gray natural cedar color.
And cattle panels are the way to go. I've already got all kinds of natural growth in mine after just 2 years. Paint them before you put them on, though. Easier to get a good coat that way. On mine, I stained the cedar black and then painted the panel dark brown and then hit all of it with a bunch of camo spray paint to break it up.
