A little exercise with the updated Miki4 and updated IBL backgrounds. The background image was from  PolyHaven : https://polyhaven.com/a/mutianyu.

Where most HDRI's are large spacious places this was a pretty narrow place, so I had to use the Dolly cam, fixed at center, to get a credible perspective and play with focal length, as one would when shooting in this confined space. 

The remaining problem is the blur in the image, un-avoidable in an HDRI taken from this distance, which is a bit too much relative to detailed Miki4. I could have kept Miki off-focus, I know. Maybe next time.
