As the author of the video says, if you like the way that you do your eye shadows now, keep on going. But if you're wanting to try something different, consider trying this. It actually did not take much longer than usual as I typically would need to apply the same eye shadow a few times at the crease to get the intensity that I like so, instead, I just applied different colors.
Another advantage that I found by doing the crease first was that my eyelid application was bolder. Normally, it might look a little muted if some of the crease eye shadow overlaps... or I'd need to reapply the eyelid eye shadow anyway to counter that. So that actually worked out great for me.
