So after asking for feedback on my Artstation profile in the Facebook community and from friends, comments were positive, but most people noticed that the bed has no shadows on the walls. This made the image look less realistic, so I decided to take their comments on board, and re-render the image with the new shadows. I learned from past mistakes, and rendered out a low-res version first to make sure that my planes aligned with the walls and floor of the image.
They did, so I rendered the final image, which I then realised was too dark in comparison to the original image, and that the bed needed to come slightly further away from the left wall.
I rendered for a final time, and took it into Photoshop to clean up the wall of the image and crop, and then updated this image on my Artstation profile. Here is the before and after.
