I like the ceiling. I think the hanging lights are too fancy and distract from the ceiling decor. A simpler light would look better or sticking with the canned lights you have. The walls have too many big, black things on them. It's hard to tell if they are windows with shade --- in which case I'd pick something lighter, perhaps to echo the ceiling, TVs (how many do you need?) or what. I'd consider a big piece of statement art in the place of at least one. If you're on a budget, get a large, high quality photo in the right colors, you can take it yourself. Sepia and black architectural might work. I like more color and more natural light. You may have closed the shades for a better picture, so it's hard to comment on the light, plus windows are a feature of your room, not exactly a decorator's choice. I would consider how to get a few small pops of color in, pillows, flowers, candles, maybe even a runner rug along the right wall. If you are doing this as part of a portfolio, the entire ensemble would look more welcoming with a few touches like someone lives there. Something on the coffee table, for example. A few books and a candle. A tray with tea things, a vase of flowers or basket of fruit. Pick one or two things and make it composed. You see this a lot in designer Houzz photos. Here's an example, you note this picture would be a lot more stark with an empty table: https://www.houzz.com/photos/21-house-contemporary-living-room-san-francisco-phvw-vp~60642

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

The living room window itself does not appear to be designed to let much light through. Please show a photo of that window, also of what lies outside the window. In the meantime, I suggest that you replace the builder-installed window with one of your own choosing. Use toughened glass rather than this heavy grill. Minimise the frame, if possible, particularly if there will not be much air coming through. If there is the potential of air but not much view, then have a sliding or bifold window that maximises the opening. On the blank wall outside, if that's your view, put up a green wall, creeper, something to improve the outlook. For nighttime viewing, add mild uplights in a natural white shade, focused on the greenery. Or else, you may be able to put up a reflective surface on the facing wall, to bounce in more of whatever light there is. Such as a coloured glass mural if not a plain mirror. Once you have maximised your window, move on to the wall to the right of your living room photo. That is, the wall that your living room shares with the west bedroom. Use a very large mirror on that wall to expand your living room visually and to bounce more light around. To cut down on expense/effort you can make it out of several standard-size sheets rather than one giant sheet. However, if that wall is to be covered with storage, make sure the front surface of the cabinetry is fairly light-coloured and reflective. Last, if not yet satisfied, consult a lighting expert for this room. That would be useful. These are fairly expensive solutions, all in all, but they should help.

Its just really messy right now. Too many colours and clashing prints. Is that Puja unit lime green? Or does it just appear that way because of lighting? Either way, it stands out like one more distraction. Pick one base colour add and add prints that go with that base. That TV unit HAS to go. So do that black metal coffee table and the carpet. I would suggest you go with a simple geometric print in the carpet. But apart from these obvious design gaffes, the structure has distinct possibilities, if you do a classic English style. The railing above adds some interest
