My office is slightly smaller 12x20. I have 4 cans on a grid in the four corners (roughly 30" out from the wall). With a desk lamp - I have plenty of light. Thinking about a ceiling fan and bed lamps. You should have way more light than you need for a bedroom. If possible switch the 2 cans along the wall (which are your pathway to the bath) on a separate switch and 3 way them to your bed and next to the bath. It sounds like the can above the bath door will work for the outside door as well. You can add a light to reach in closets ((We do a flat strip light mounted inside, over the closet door). Most fans have a handheld remote control. You can 3 way the 2 lights on the opposite wall to the door and bedside as well. With 9 ft ceilings- you won't have enough light for reading, but the table laps or wall mounted lamps will be useful there.

yeah i will change the lamps and the bedding once the curtains r ready....i have a window behind the bed so i will havee to have curtains....becoz i dint find any good navy ones ( i looked in a dozen stores :/ ) so iv thot that ill do some layers in the curtains...may b a plain navy blue ( behind )with the black n white in pic 1 or 3 (infront ) ? lamp shdes navy...n bedding will hav diff colour pillow sets( white blck blue n coral ) ?? will it be too matchy matchy ??

As hatetoshop mentioned , moving the bed to the gap between two window is would be right choice. as in current placement you have windows above your head which does not help for a view and looks odd. you could place double curtain rod or use existing curtain rods and add additional sheer /thin curtains for additional privacy during day as well as light. In future you can add two bedside tables as well and some bedside lamps. In India we are still not used to lower lighting (floor lamps, table lamps with warm day light bulbs) but trust me,it will add new dimension to your bedroom. Also some wall art. example a well framed big size ( 2ft * 3ft) art poster above bed (cheap way to add life (I wont use word "Class" (find it too much)) . Also in future you can think about having a pair of bed sheet (to sleep on ) and bed cover/spread (a good quality cotton one) to cover the mattress during day. And a dhurrie runner would be a good addition as well. All above wont cost too much and maybe little bit investment in quality material can be good as well as u don't have to change these often and can be a long term solution.

To add, the window you see at the end of the passage is the light source I am talking. The cabin is in the end, the same room with the window. Its west facing so after noon the light is strong enough to come out till the reception, , form where I clicked the first picture, I am I have bee able to explain well.
