C4D placement is decent. But render needs some more blending. Adjust the colors maybe.

3px Hard Brush, possibly with Scatter 1000%. Alter the Brightness under Color Dynamics. You can also add Outer Glow to the layer. Play around with settings, possibilities are endless, just make sure it fits the tag.
