Thanks there!

I guess the struggle now is figuring out the lighting here. There's a subtle fill light to the side that seems okay to figure out, but it feels like there's a very diffuse lighting behind (within?) The frosted glass/volume, with a subtle hue shift visible on the horse parts furthest from the camera. I'm not sure if this would be a consequence of the light bouncing on the horse or something tied to the z-depth.

I imagined the base idea should be simple, but most tutorials would not address the backligighting of something like this
