The bookcases were moved to the back of the room from the front and split apart with a small dresser. A corkboard was also used to spread them apart. In order to maximize natural lighting, he moved his desk from the back of the room to right next to the window. It was placed perpendicular to the window. His work area is a lot more functional, since his bookshelves are right to the back of his workstation. His main dresser was placed against the wall to the front of his room, where his bookshelves originally were.
This allowed him to showcase some of his creations, including a piece of art that he made from discarded CD/DVDs. A lot of the work involved simply cleaning up and throwing out some of his stuff. There are some ways that he could have added some charm to his room. Adding a nice table lamp would have been a good idea. That would add some more lighting to his room, even though he already has a lamp. He could have created some more ambient lighting using IKEA LED Dioder strips. The bookshelves could have been kept together and the small dresser could be used as a night table. The extra lamp would be placed onto this to help him work from his bed or read, when he wants to.
