Basics first, please get rid of any plastic furniture like that chair. secondly all table tops need to be cleared of little mirrors, table clocks etc. just place three most loved items of your choice ! Arrangement can also be improved the table could come on the side and bed could be centred a bit better (along the window behind it). Walls can be painted a neutral shade like light beige with a rug of your choice on the floor (contrasting- like red so that the pink curtains could go with it)If you could change the curtains then the best option would be to pick a solid colour of your choice and a matching rug (blue, red etc whichever is your fav colour but please avoid printed cutrains)

I have 300 sq.ft bedroom, then it have double sized bed,one alamaara,one round shaped table,cooler,chair,table fan and final cloth hanging.how can i arranged?

visualizemaven- an almirah is a built in ( often wooden carved) usually floor to ceiling cabinet ( closet).

work in three basic steps. 1. Paint the walls in a neutral shade like grey or beige.2. Go for wooden furniture in polish like walnut or pine colour (light brown). 3. Then choose any accent colour like red, navy blue, wine chocolate etc of your choice. Buy curtains, rugs and bedsheets of this one shade in solids. Then go for a couple of accent pieces like two frames or two lamps in white, gold or silver (again of your choice ). Done! this can be completely transformed very easily only by chanign the accent colour once you are bored..! all the best..
