I'm not sure how well it glistened, but after I added layers of color, I added touches with a white gel pen for breaks in the water. It was my first attempt at a reflection card too. Don't work too hard at it, since it is supposed to be just an interpretation of the real thing.
For the blues I used a sponge...I don't have a stipple brush and liked that a sponge let me control where the ink went. I could also change the pressure I was using to apply the ink, whether it was more of a sweeping motion, or a dabbing or scrubbing motion. Warning though, I had blue fingertips for a couple of days.

I haven't tried a brayer yet...still getting used to how that distributes ink...I will have to try it out.
Here's a link to my card if you want to see how I tried it:
