Gee whiz, Mr. Bautsch...it's gonna be hard to follow that! I agree with most of what you said. Congrats on posting your first photo in the critique forum, DaveH. It's a big step to put your work out there for others to give feedback on. Shots like this are very difficult, and anyone who has tried it can appreciate the amount of patience it takes to capture one. Kudos for sticking with it.
Did your purple paper have glitter or some other texture on it? It's a cool effect w/ the bokeh. Purple is an interesting mood color, and blue would've been another good choice for this shot.
I think your depth of field is a little bit off, maybe by an inch or two. The water droplet is perfectly in focus, yet the front and rear edges of the glass are not. For me at least, I think there needs to be some separation between the glass and the background. Here, they appear to blend together.
