My $0.02:
You've built a beautiful pond, with clean lines and a somewhat "formal" look, versus a "natural" look. I'd recommend that, for your falls, you stick with the same style. I think if you go with the dry-stacked stone look that other posters have shown (which looks great if that's what the rest of your pond looks like), it won't fit with the pond you've built.
Why not stick with the same type of stone blocks as you used for the pond? If height/cost is an issue, look on craigslist and in the local paper to see if you can find a set of concrete stairs someone is getting rid of for cheap. Haul them home , then hide them with one layer of the stone that matches your pond. For your falls, stick to large flat rocks with straight edges - basically having the water come down a paved course and a series of semi-formal "stairs".
JMO.
Love your pond BTW
