EXO Monster | Monsta X Hero Mashup Creation

I wanted to remake my mashup of Hero and Monsta X and decided to film it for those who are curious as to how I make my mashups. I'm completely self-taught and don't follow any specific guidelines or procedures. This is just how I do it, and is by no means THE way to do it. In fact, if you are interested in making mashups, I would consider actually looking up proper ways instead of my mess haha.
