It is starting to look very nice, but since the "woods" is the main theme here, I think you should put more effort to make the trees look better.
a) the models are not very great - the bottom branches look strange, low poly
b) the blurry background is really bad, it doesn't look natural, and there should be virtually no DOF when shooting with such wide angle
If you are having problems with hiding the background, you could put some big objects in the background, like some large rocks, or you could also try to make the ground have various height, like a side of a hill.
