I have a suggestion for showing off your work. You want to choose the camera angle and the lighting to emphasize the most detailed portion of the image. As a result, I would actually have put the *handle* in the foreground and the saber-beam in the background. I would also have increased the lighting around the handle of the lightsaber.
The beam of the lightsaber is very simple and (visually) very boring, by design. Since you clearly put a lot of effort into the handle of the lightsaber, you should be trying to show us as much of it as you can! It's too small right now, and I can't see all the detail that you clearly designed into it.
In the same vein, I like that water effect, but I can't really see it. Those reflections are really awesome, but the overall effect is hamstrung because you only have the one (very dim) light source.
In summary, my advice is to add some lights, move the camera, increase the image size, and then re-render. And please post the new image so we can see!
