Keep the wall opposite the entrance free and light colored , add any eye catching fixture or full height mirror to visually balance the narrowness at the entrance

Can you please share the pics and floor plan to evaluate your situation..

This is the floor plan. Every bed room has a wardrobe side wall at entrance measuring at least 2.5 ft width. I also have loft running above the door and the entire entrance looks intimidating. All the bedroom doors touch the wall unlike shown in the plan for the 1st bedroom. Help me with innovative ideas even if it means extending some part of the wardrobe raft to other areas of the room for integration.

The layout doesn't seem as bad as you think. The sides of the wardrobes are part of the entrance-way and to your side as you enter each room. That's at least better than the side *facing* the doorway, another common layout. You could add some wiring to place an LED spotlight just above the door way, aligned to the middle of the depth of the wardrobe (ie, roughly 1'-0" away from the entrance door frame). This is assuming that the loft also runs over the doorway. You could also cover the side of the wardrobe with a full length mirror. Or you could paint it the same colour as the wall on the other side of the doorway. It is not really a tunnel like look when it's just 2'-0" deep, light in colour or reflective.

Thanks GJ Studio. Very thoughtful. Also instead of full length mirror, will ones with design or patterns like the attached pinterest design a good idea? Is it also a good idea to continue the rafters running between wardrobe and loft across the bare L wall?

Such elaborate design on a mirror will further crowd up the space. You need something unobtrusive that takes your attention away from the wardrobe. I didn't quite understand your second question. Which rafters?
