Dawn over a Carboniferous landscape, some 300 Million years ago. The trees are Alethopteris serlii, an extinct Kind of tree-like fern. Tree models are from xFrog.

Nice start. I think the ground needs work, it's colour seems at offs with the veg sitting on it as there would be low cover plants/grass etc. If you need models of grass Dune has a free pack over at NWDA that has 9 or 10 models in it and all are awesomely useful.
