Great light, great colour, great atmosphere, great grass. I think that maybe the falls should be more prominent than they are, however. Maybe zoom in on them some.
Also the foreground needs a little something. Some rocks, perhaps? I'd recommend the pack I just made but it doesn't look like Danny has it up yet. Maybe you could use some fake stones or something. I really like the grass, but it needs a little context. You could also place a little wildlife maybe, just something to draw the viewer in would finish this piece off.
