Many thanks for all the great feedback… the jury’s in and it’s indeed that way up!
As it happens, that’s the way I worked it: My reference image had some warmth in the bottom right section and I exaggerated this in my painting. I drew somewhat on an underlying image on the previously-painted canvas (see In support of old canvas). Some find it looks like a campfire.
The other way up, it seems more like warm light filtering through trees…perhaps altogether more tropical!
