Yeah, I placed my comments in my head and after a while I checked Piwlady's comments. i totally agree. This contains a bunch of doodads for no reason.
Rules you need to stick with:
1) Do not use for ANY reason mushrooms. They are pathetic; honestly, if I see a good terrain, that contains mushrooms, I call it a) lack of taste and b) unbearable to watch it anymore.
2) Animals should not be used in a scenery in a pack. Since this is not playable, you need to stabilize a nice camera angle and just add a deer's figure somewhere in the forest, not that ugly bear looking its reflection upon the water.
3) I know you were going for a magical effect, but the purple trees just don't fit. Find the line between magical and tasteless. The whole scenery is a product of green, so those purple trees look out of place.
4) Fog = Magical. Also, use some glows (Glow model, Ultimate Terraining Map).
Forests is the most overused theme ever in the Terrain section. If you want to make something of this concept, it must stand out.
