Summary
Keep bed, night stands and lamps in same position (not much room to make changes). Remove chest and place a thinner TV stand or just mount the TV on the wall. Then get better decorations such as portraits of things that relate to what I'm interested in, then replace linens with newer and more lively colors. I will primarily be keeping the room the same except with changing some furniture and adding decorations.

What should I upload in this Develop Solutions step of the process?
Consider uploading images (JPG, GIF) of your rough digital or physical study model. It's ok if your model is still a work in progress. Show an axonometric or perspective view with people, which will help others understand the scale of your classroom.
