I am really liking how it looks with the silver tones on the black background... but in general, we usually use the logo with the white or clear background... Try using some color on the wording when making it in a white background. Also, try making the actual CG on a different font. The first font looked great, but I am not such a "script" person...
Any chance you can do the circle something else, like a camera, a shutter, a lens... something very simple (and thin, like the circle) and elegant. Don't alter the black background one... work on a white background. Ultimately, it has to pop in white background.
