I always try to cover the horizon when I use Bryce because its unlikely to be able to have an unabstructed view for that far, but that's just what I do. That's pretty good though especially if you are a newbie, you should have seen the awful Bryce renders I did when I first got it. But you never will because I swiftly deleted them. I agree that the wolf is a little stiff too. And as for the tree, the leaf textures in Bryce 5 aren't very realistic at all. I usually change them to the trunk textures instead. Oh and you better do more because that's the only way to get better, except for some sort freak accident that makes you have superhuman intellegence, but those kind of things just don't happen often enough for my liking. Oh well.
