Applied the altering of colors and different timings to the electricity.
I like the flow better because it eases out into dissipation alongside the smoke.

The smoke should be less bubbly. It should dissipate like streaky mist, not cartoony clouds. I fix this by connecting the shapes to form longer lines.
The dissipation should follow a curved pattern that resembles its silhouette and flow direction. So for this example, I could have make it curve slighty in-out ward from the center.
