The blue one isn't great, I was going for a rounder/softer look it kinda just looks off.
The blue one almost seems more like sparks. I think it just needs more flow to the direction of the particles. The red one shares a similar issue but it makes up for it with the larger sweeping particle, it sort of pushes the whole direction of the piece to the right.
very nice small animation man, i am not gona lie might us as reference at some point
