Which direction will be based on?

[myfs_81564]

Dear Mr. Cecil Lee,
My Kua number is 2, My Eight house chart is Southwest.
The main door of my house is in the North direction. My master bed room is in the Southeast section of the house (which is one of my bad directions) and attached to the bathroom/toilet via an open space between. Please help me to clarify these questions:
1. Does the curtain hung in the open space between the bed room and the bath/toilet room will enhance the good sha in the bed room? Currently I hang a thin curtain in this place and always close the toilet bowl lid and the toilet door when not in use.
2. If I like to place my bed in the NE section in the Master bed room, should I use the NE computed from the central point of the house or the NE computed from the center of the Master bed room?
3. Based on my Master bed room layout attached, is my bed considered as pointing to the NE direction? Is it OK if a partial of the bed foot pointing to the open space mentioned above? Is there any other direction suitable for my bed?
I'm very appreciated for your advice. Thanks in advance.
