coffee? tea? me?

I'm still playing around with off-camera lighting, and starting to wish I had a second flash ... DAMMIT!
But I had this idea of taking a backlit shot of an espresso pour, so that the machinery would be all silouhette, on a white background, the espresso pour being the only colour in the image.
I took some test shots, with just water coming out of the machine into the cup that looked promising, but when it came to a simple espresso, the pour was too dark and not see-through enough, so everything was just black.
So then I thought I'd combine the two elements - water pouring looked good but boring (who wants a cup of hot water?), espresso pouring looked bad but tasty. So then it hit me - espresso pouring into water, like making a Long Black.
so here it is - the first drops of espresso pouring into the water. In a wanky/arty moment, I titled it 'infusion'. click to enlarge.
Any tips? thoughts? criticisms?
