Riot Beardilocks, vfx lead on skins for League here.
This looks super awesome!
You’ve done a really amazing job capturing the thematic. The shapes you’ve got in there are great, and there’s some really cool dynamic motion on the trails.
If I had to give some constructive feedback though, I think you could adjust the colours of the trail slightly.
Increasing the contrast on the ball itself by making the values brighter in the glow around the ball will help to improve the visual hierarchy.
Additionally, I think something the concept did really well was use a very wide range of hues, going from yellow to saturated orange, through violet into purple.
I think you could push some of the hues at the dark part of the trail to include more blues, and get some more saturated oranges near the ball.
Overall this is some fantastic work though, and these are just minor polish points. Great job!
