Most of that time was spend building the engine, and coming up with ideas. Heck, by E3 2009, if you remember, they didn't even have an art style yet. My bad. At the same time though, TP's artwork is kind of gray and dreary. It's the reason why some people seem to think the entire game is all gray. Faron Woods wasn't perfect. But I think it was solid from a level design perspective. Just not as good as the idea of a real, open forest.
