wildebeast in the great fields

I’ve seen somewhere an SVG image of a wildebeast standing on a hill in a field with lots of grass, I thought it could be cool the take that idea and make a 3d version of it;

the sky are from the sky gallery by [email protected] .
all the rest are mine;

I have a couple of problems with it,
first is the grass, which doesn’t look right (as if there is no antialiasing).
the wildebeast is also not perfect, I will upload an image featuring it only with some close-ups and better lighting, shortly.
