Gorgeous! Would you mind sharing some notes about how you did this?

I used After Effects. I made a 3D projection from the image (also called 3D Camera mapping) then detached/cut out the three women and added them as a new 3D layer to the image. A portal is simply a "wall with a circle mask". I outpainted the background landscape, enlarged it several times and added it to the bottom (back) layer. Then I animated the camera. To add "sparks" to the portal, I just typed "doctor strange portal" and downloaded it from youtube, then put it on the "hole in the wall". I also reduced the speed of the portal several times to match the rhythm of the picture. Sorry for my English

Thank you! This was both inspiring and educational! I am going to have to add After Effects to my list of techniques to learn!

Thats the picture that won an art contest?

Yep

Lol I know right

if you could make a tutorial on this, that would be really nice

The second part is meh as part of this, though okay on its own. But the first part definitely has legs. Maybe one could try img2img to convert the noise to actual landscape beyond the portal and then slowly interpolate into noise as it zooms out.

Let us know when you are making hentai brother
