Tell me my friend what is the interesting part of it?

I find everything that differs from the crowd interesting even if it is far from what I like, I try to give a more realistic look to my girls and I often use hdri both for background and lighting and to speed up and use resources on the character. so I found the tutorial interesting, I hope I answered your strange question ...

Yes the tutorial gave me a lot of ideas how to approach my renders differently There are so many many many things you can do what that goes. Especially when it comes to light and hdris
