Our new environment

Dear Cecil
Your site is well built, I found some answers to my problems but I am still
puzzled with our new environment.
My in-law just bought this house and we moved in with her. We stay in the
master bedroom which I know there exists some problems; yet I know there's
nothing as perfect. My husband's career has been very bad these days.
Hence, I am attaching the floor plan of my bedroom hoping you can help us.
My husband's birthday is April 19, 1953.
My questions for my bedroom are as follows:
1) If we don't want to remove the mirrored cabinet doors (my husband is not
convinced yet, and I want to prove it to him) is there any other way we can
do?
2) He sleeps on the right side of the bed, hence his feet point at the
bathroom door. What can we do?
Also, for downstairs (please refer to 2nd graph), do you think we need to
cut down the tree in the front? (It's a very small tree). In addition, is
the main entrance in line with the patio door creating a bad qi? (We
usually don't use the main entrance, we enter through the garage).
I really really appreciate your help.
Regards
Zoe
