Or perhaps more precisely, that massive fake rock wall in the rear is over-powering. The rocky slope is quite nice.
A tall fence hidden in the "forest" would have been so much more beautiful.
Even if it couldn't be hidden, I'd take a simple wooden fence (even with the addition of mesh if required - it'd hardly be visible at that distance) over that ugly wall of mock rock.
I'd agree with Zooplantman that the rock on the slopes, by contrast, looks quite nicely done (as usual, the bit where they use fake rock as if it were real rock looks better than when they use it as a glorified cake icing - some day exhibit designers will start to spot this!).
