Here is the link to his image, I have been trying to figure what kind of perspective his using.
I love how immerse you get to feel by watching each of his image.
I though of it as a 4 point perspective, but by googling there is no reference that looks like it.
The keyword I used in google: curvilinear, swirl background, curl background etc.
In naruto also, you see this kinda effect in the opening songs. So I was wondering is there a name for this kind of style or effect.
I'm currently learning perspective by the way :p
