I just finished taking a beginner's Bryce class, and (to echo Stephen Ray) one of the main things I learned was that it's important to manipulate textures and skies. Your sky, in particular, looks as though you've used a preset without altering it even a bit. You might also want to change the POV somewhat so that the horizon doesn't (predictably) cut right through the middle of the image. I think the cross-hatching look of your rocks takes away from the realism, as well. Maybe try a different texture or fiddle with the frequency in the Mat Lab? One other thing: where's the waterfall coming, since there isn't even the hint of a hill or mountain in the background? Unless, perhaps the source is an enthusiastic spring ;-) I'd also suggest a little variety among the trees. It's too obvious that you've used the same model one for each tree. Hope this doesn't sound too negative. I think the basic image is quite pretty. I especially like your use of the bridge - makes me wonder who uses it. And I admit to feeling a bit foolish, as a beginning Brycer, giving you such a critique. So please take these words with a gigantic grain of salt, if you wish. By the way, I tend to avoid doing larger landscapes like this myself because of their inherent difficulties - LOL! My scenes (most still works in progress) are all very close in. Now I'm gonna go check out that link Stephen Ray provided and see what I can learn to help myself!
