looking good, here’s a few thoughts/comments:
i generally like to have a subtle ‘something being drawn in’ effect when i’m growing a magic orb or sphere - from sort of 1-2s in the video. just some simple lines or swirls into the centre of the effect to show gathering energy.
the ring that bursts at about 3s doesnt seem to have the same colour gradation as the rest of the elements - it seems a bit flat in comparison.
the impact spikes at around 4s all seem about the same size which doesn’t imply a huge amount of energy and dynamism - some variation in size and timing would probably help here.
also the rings that scale up and fade out seem to opacity fade rather than alpha erode - probably better to erode these out instead, very few magic things look good with an opacity fade imo, compared to alpha erosion.
i’d probably add a bit more history type elements to the burst and trail too - just little sparklies that linger around a little longer than you have - ideally i’d still see the ring when the projectile hits and still see the trail when the final flames are still burning out i think.
lastly i think you can really push the glow and emissive of the colours - at the moment nothing is really standing out as really powerful glowing magic.
there’s a good solid base here, but i think with a little bit of polish it could be great - keep up the good work!
