2 things wizard, 1: the beam charge aura should be much bigger, proportional to the one in the anime.
2: im not sure if its possible, but if you you look, the charge is more like a ball with a pulsating ring around it, and in your wip, it looks very flat, so make the center of the charge brighter, and figure out a way to trick out brains into thinking the center is mor sphere-like. (oh and also, it would look realer, if you could make the beam trail almost a translucent (partially transparent) shade of white, so people can control, without making it look too diff from the anime, and, mabye later make a big bang version, i have a feeling that would be easier to make look real)
so make the center of the charge more round and brighter, make the aura charge thingy proportionate to the anime, and make trail translucent white!
and kudos for putting in so much effort to this!
