Something always bothered me in Oblivion. And that was the trees were usually pretty small, especially the redwoods. I've lived near the world's largest redwood forests, they grow so tall that it's hard to wrap your mind around it. "Why do all the cars look so tiny?" is what you find yourself asking. Skyrim looks to continue that tradition. I realize trees in the far north actually tend to be fairly stunted, but I still think it would be cooler to have something like this:

I mean, we have dragons and magic and etc. I'd just like imposing forests to go with them.
