This will help get some light into the middle of your space. http://www.westelm.com/m/products/overarching-floor-lamp-antique-bronze-w890/?pkey=cfloor-lamps You could also do end tables or a console behind the couch and place table lamps on either. It doesn't look like you have any seating near the edge of your space and your existing lighting seems to be positioned at the edges of the room. So I'm not sure if sconces would help much.

Pls give some idea to replace the red marking wall with any moveable object to open up lobby space thanks Neetu Singh

Neha, That's a luxurious space that you have. A lot will depend on the placement of mirrors here. Distance is farely safe but you may have reflections bothering during night time viewing.Best way would be take a small mirror and check it or you may move them slightly off center.
