Love watching these updates and thought I would throw some CC in the ring.
Perhaps have the smoke expand at the end, rather than shrinking inward. The sparks have so much power, the smoke would be a nice follow through on that energy.
Similarly the scorch mark could almost look like a molotov / cartoon impact in sense that it radiates from the center.
I would also suggest less lightning but more pronounced. At the moment it feels a little noisy, like it’s fizzling. I would recommend a one, two punch combo. Ie : Strike, pause, pop, pop, pause, pause, pop, pop. With the later two being slightly smaller. The silhouettes would read quickly and nice.
Hope that helps :)
