Not sure how long your exposure was (my Exif Viewer is no longer working) but I think a bit longer may have looked better. Like you say the water does look a bit messy, a longer exposure would probably have smoothed it out more.
I made one my self one with a body cap, drill, tin foil, a pin and some insulation tape ... It worked but I had trouble working out exposure without knowing what aperture I'd created ...
It's a basic light meter ... Passable for everyday photography in non complicated lighting situations (just like the iPhone is funnily enough) as you can see, it's range goes to very small apertures and long shutter speeds so it's perfect for this sort of application I reckon!?

I would have liked to have been able to wait a bit longer for it to get darker but A) the sunset was fading fast and B) it was blooming freeeeezing, and I dont really feel the cold that much!
I hadnt really planned to do the shot really but found a perfect perch for the camera on a concrete wall and decided to give it a go, even I was getting funny looks, kneeling on said wall lol. but its something I want to keep on practising at it and it did go a little way to curing my shyness with the camera in public when theres loads of people about!
You would be surprised as to the colours you get, or rather the camera sees after the sunset. I would go back again fore shore (hehe). I have a contact on flickr who does alot of this type of work. I'll dig him out and post a link.
