There are several issues with the reflection:
1- The image in the reflection, where the seat and the cardboard are located is not the right one.
2- Sophia's legs are not the right ones in the reflections, it should be the other leg in the foreground.
3- where's the pink light in the reflection ?
2 - To be honest I was too focused on Sophia's butt to notice the posture
But it does not seem too odd to me, her right leg is a bit bent forward but not to the same extent in the reflected image. But other than that I doesn't seem odd to me. I would rather be worried about Sophia's right forearm, isn't it a bit too long or oddly shaped?
1-3 That's what I was talking about in a earlier post, there is for sure another poster in the room that is only visible through the mirror and it is the one surrounded by the pink light. But from the mirror image it appears to be hanging above the seat and the cardboard, but in reality there is the mirror with the laps. We cannot see the reflected image of the mirror with the lamps because it's (potentially) occluded by Cathy and Sophia's arm but the poster it seems to me aligned with the seat. Maybe it's a perspective effect due to the perceived compressed depth.
