I made an experiment to see which one is better, the original or the monochrome, but I think the original is better.

I think I prefer the monochrome.

The biggest challenge was keeping the camera straight as I don't have a tripod (yeah, should stop procrastinating and buy one finally) and move it accordingly, when my human sparklers holder moved the sparklers

Hey I will get you arrested and sue you for procrastination .lol..better get up and get the tripod as soon as possible before I arrest you.

Selling sparklers is strictly regulated in my country, which means sellers are allowed to do so a couple of days before Christmas and the period ends with New Years Eve

It was regulated here too for security reasons..
