Below is the floor plan with the suggestions you made. I drew them in red. The bench by the window is really nice but I don't think you have the space to put one. To put one you would need to build a 2 ft wall and have the bench there but it would mean you have no room for a second night table.

As for the shelves, I drew them in red where the television is. If the shelves are 1 ft deep, it means that when you enter the room you would need to go around them to get to the closet. I believe if you really want them, you will need to move the door for the bedroom or make the shelves 6 in. or less.

Also, you mentioned that one sink was good. Your vanity is wide enough that one sink alone would look to empty. But I see 2 options: one is to have to sink and have a 18" wide storage on top of the vanity or you could have one sink with 2 storage 8 ft high by 18" wide. See the 2 options below.
