How to do Realistic Droplets on Leaves

A quick critique .. there is nothing in the world better than a tutorial that not only works beautifully, but doesn't require three weeks of trial and error to make it work the way one had hoped.
This is well written, clearly written, wonderfully clear illustrations, and educational in the ways of water flow on leaves.
Giving you a:
5 on vision .. obviously you have very clear vision on how to write and illustrate a tutorial
a 5 on originality as I've not seen a simple sensible tute on this subject before
a 5 on technique .. which is important to someone who is still learning, no complicated stuff to confuse!!
a 5 on impact because I think it builds on my courage on trying things like this, and encourages inventiveness to create techniques of my own.
That's the opinion of one somewhat of a novice to this kind of thing, and maybe not as quick of a critique as I has planned (:
