I always wanted to make my comics like this, I love that cinematic style.
But a big part of that "cinematic style" is the very wide aspect ratio, and webcomic sites aren't horizontally-inclined. Neither will it be friendly for readers, who are most likely looking through their vertically-oriented phones.
I've tried this in one page, where there were very wide shots. It didn't sit well. Readers complained about it not being legible because of the points I've made above.
