Bathroom door facing room door facing front door.All in straight line. Is this bad feng shui?

Well, I'm afraid that the answer is yes. Bedroom door should not face the bathroom. Besides, the front door is no good to see bathroom/Bedroom. But don't worry. There are also several ways to change better.
For front door, you can put some red decorations, green plants, and classy paintings or calligraphies near it.
For bathroom, you are suggested to clean it every day. It should be dry and airy. Decorate it with white, black or blue and use marble or granite ground tiles.
For bedroom, you can choose soft colors to paint the wall. And buy a folding screen and put it between bedroom door and bathroom door. Buddha paintings and portraits are avoid.
