I tried to capture the look of the tight stream spreading out into a haze at the end. I think it reads well but doesn't really get the look of the reference video. Mostly I think I needed to design my textures better.
But let's not dwell on the past! Here's some reference I'll be using for my next particle(s), electrical sparks:
This video is long and poorly captured, but there's some cool shots of sparks running along the length of the power lines. I like this one for the interesting colors you get in the sparks, and the way it moves along the wire. I wanna make that.
