Feng Shui for a dental clinic

Hello, this is for an advice about my dental office. This is in shape of a diamond and the land is in triangle shape who ever looks at this, they start giving there own comments that some thing is wrong here or there. This is a rented one. Please give me some suggestions. The main entrance is towards north.

There is an article you can check. There seem a major problem and you should go for professional Feng Shui for business consultation. I will need the floor plan or diagram of your clinic along with your date of birth. There will not be any need for civil changes so the question of your property being on rent is irrelevant. If need be I can make a personal visit too.
