Dark Magic Blast - Looking for Feedback

Hey everyone! I’m currently working on a Dark Magic Blast effect and I was wondering if the way I made the impact seems effective currently. I built up anticipation with the ball smashing down and impact with the blast out and the particles flying out. What do you guys think of it? Is there any way I could make it stronger without cluttering up the piece?

To me it feels like your expansion is sligtly too fast. I would slow it down ever so slightly, right at the end.
So your expansion curve of the circle would be slightly more like this:

That way it feels strong at the beginning and then slowly fades away.

In addition, in general, I would add some lingering, softer shapes to the entire effect.
