Because I had a design idea, and I couldn't stop at 3.
I wanted to go for a kind of spark-like effect and then a softer starry glow in the tail. I kind of wish I could feel that wispy tail, I have no idea what it would be like.
Probably it would feel like space itself, I guess. However that feels.
Anyways, yeah, here's my 4th entry! I hope you like it!
