Is this still a low fry?

Song: Sulfur by slipknot I'm trying to push more air and focus on how I emphasize the shape of the mouth to get the tone I want, but when I push too much air, the frequency changes and it gets to a point where my chest would hurt or my tone will break (change/uncontrollable)

I've seen chris liepe and will Ramos' video about these and they emphasize heavily on comfort rather than raw power, I'm also quiet and soft spoken in general but I've seen other youtubers that can project loud and maintain their tone.
