Looks pretty sweet Henry...
I like big renders too

But..., I think it would be nicer if you could render it with higher settings, or is it flicker compression going on?, instead of rendering it bigger?
The grasses and bushes look pretty noisy for instance.
What render settings do you generally use?
Besides a bit more size-variation I think it would also be nice to add a rotation on the x- or z-axis for the objects, because everything is standing straight up.
