Sooo this is just a render on a background?
Try blend your focal a bit add effects areound it such as fractal, c4ds or brushes. Your text is not needed here but it does kind of hide the negative space a bit. But if your going to ever put text on a tag NEVER put outer glow on it, the chances of outerglow looking good on a tag is like 0.01%

Overall: Fill your canvas more with effects, work on text and work on blending your focal. (blending your focal ties in with working on effects)
