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.

I like the 4th one the most, however it is very difficult to see the shades as they really do not show up in your photos. Look at lamps Plus.com 'sale' . be sure to get ones that are between 26 & 30" tall. Your side tables can be different, in fact should be, but the lamps should reach close to the same height. No more grey please.

Paint the wall behind the bed the purple I have shared. Paint the headboard and door the gold from bedspread, white or grey. Pick up two standard pillows too to add to bed. Add a purple shag rug. Hunt the Internet for abstract glass decals to adhere to walls over bed. Your photo collage should go on another wall- over bureau perhaps - as it is currently hung to high. Putting it over the bed also makes it hard to see photos, which is the whole point. Check out IKEA for fun, inexpensive bedside tables ( not that color).

your choice of furniture pallet is realy beautiful.
