Not bad but monocular depth estimation has gotten pretty good all around. I made these similar images with basically no expertise, no manual mapping, just trying random single image depth projects from github. I kind of just went with whatever I could get running quickly, didn't even evaulate the quality other than cases where it obviously didn't work.

(Sorry for linking a million tweets but I didn't put these on a blog or anything, that's the only place they exist.)

Your version does look better though! But I was impressed I could just run random images through depth estimates and get anything cool like this.

I would love to your method take on some Escher paintings, can you try it for me?
