I’d rather have a smaller bedroom than work in the bedroom. Many ID and feng shui masters have come out to say that working in the bedroom is not ideal and brings about a different energy to your resting space. If you work from home often enough then it really is discouraged. If you have no choice, I’d try to partition or silo off the work area.

U might need to consider the placement of your aircond. What is the mounting height of your ac and does it looks good with a slightly lower ceiling in your working area?
Same goes to your tv position. Is there any better way to place your tv as your bed is not directly infront of your tv.
