People in the comments pointed out that the effect is too big and distracting, so I scaled the whole thing down a little. Also made a new demo for it. However, I haven't changed the animated thumbnail, because I want the effect to stand out a little.

The effect still looks big, but that is what I want it to look like. I am also being realistic and I don't think that this effect is gonna make it into the game (this is also the first time I am doing a thing like this), therefore I will not change this effect anymore.
