Love black and white pillows with a brown couch. Throw a printed teal pillow on your non leather chair and hang Sam/tyler pic in that room to tie in teal rug. Then add white tv console and switch out a few shelf items with some black and white items.
[DISLIKE/DINING ROOM] This seems more for show than to actually live in. This is really basic in my opinion and it looks bland and uncomfortable, if the chairs were coloured it would not look bland and more fun.
