I would brighten it up by painting the walls a more neutral color. Adding new bedding and fun pillows, artwork, etc. will add punches of color that will work nicely with the neutral backdrop. As a student I know designing in a budget friendly way is important. If you have an Ikea, HomeGoods, Gordmans or At Home to shop at, these are all great places to pick up interesting and fun pieces without breaking the bank. As far as space planning, from the picture it looks like a fairly long/narrow space- I would keep the bed at the back, back a sofa up to that and add a couple of comfy chairs and maybe an area rug. Dont forget the artwork too, this adds a very important layer to your space. Hope this makes sense and helps!

Firstly, one can play a lot with furnishings if you are staying in a rented apartment. those white walls are nothing but a clean canvas and you can really use colors through your furnishings like cushions , upholstery, curtains , rugs etc to add colors . Secondly , instead of wall shelves etc add small side tables on emptycorners you get etc which gives you platform surfaces to display your nick knacks.. You get many freestanding display shelves online and in market where you don't have to use screws in wall. :)

Hi Shikha. You have great space. You can workout in segments if there is the budget issue. Like, go for some light weight sofa (like with wood frame), along with arm chairs and ottoman. This will not only rejuvenate your space but also cut out the monotonous setup of your space. For accessories, you can go for contrasted cushions and vases, planters and frames for the wall. Don't forget to tie up the space with a carpet that matches to your space. The large collage on the wall would be better if put into small frames. Also attached some reference pictures! If you are still confused over the space, please reach to a designer! :) They will surely bring the vibe you are looking for your home!
