Hi, You don't say whether construction is completed and you've moved in yet or if you're going from this plan only. If so it's a good idea to live in a space for a while before knowing if your changes are really necessary. And you can change around your dining/drawing areas easily until you feel right about it. I'm not so sure if it would be a good idea to chop up the space like that, and the two furniture arrangements serve amply to define the spaces. If you are finding a real privacy inconvenience then here is a nicer solution i think. A semi transparent double sliding door like this across the study area opening would give enough privacy while at the same time allowing light to show through and not totally closing off the space :
