Yes the asbury is a bit of a small sconce for that mirror. Also the wattage of the bulb at 60w may feel a bit dim. Something more like the Arcadia from Norwell would be better. It s a bit chunkier and the glass shade will arch down. And its a 75w regular bulb which give you better light! http://www.norwellinc.com/index.php?option=com_content&view=article&id=1386%3Aarcadia128785-pn&catid=34%3Aadmin&Itemid=39

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.

I agree I need a customer wall to wall solution and maybe a full mirror for a small bathroom would look good. The challenge coming are those electrical points. Also someone guide as to what is the right width of the mirror I should put incase I just decide to put mirror over the sink? Is there enough space for framed mirror? The width of the countertop is 26 inch and the height from countertop to sconce is 52 inch. Thanks a lot

Why not paint it in a pastel colour? Add a carved chest that doubles up as shoe rack and organiser to store your shoes below and hold keys and bills in top drawers. You could hang a painting or a statement mirror above the chest and highlight with wall sconces or beautiful table lamps to shine a soft light around it.
