I had purchased hafele hob 10 months back... I got it serviced 6 times... Now i requested for replacement with new one... Still they have not attended my request...

If you want to let in more natural light, I suggest either solar shades or sheer shades. Both let in plenty of natural light without sacrificing privacy. Here are examples of both: http://www.blindsgalore.com/solar-screens http://www.blindsgalore.com/sheer-shades

A rug with a horizontal pattern could help along with a false ceiling above in which you can install a line of recessed lights. The tiles and border on the walls suggest that this is a passage in a shared washroom space like a health club. It looks a bit cold for that reason. So hang a lot of warm framed prints to make this space more inviting.

Suraj, If you have access to the room that you shared earlier you can try seeing the flicker effect at night time with both lights and fan being on. If the lamp has a 360 degree light spread it will cast the fans shadow on the ceiling and when the fan is turned on it causes a flikr effect. I personally find it a distraction and at the same time many would not even notice it. Take the pick based on your usage. Wall mounted fans and recessed fans can also be explored.
