Houzz is the new way to design your home.
This shade of blue (walls) goes well with red.
Smaller "tufted" fabric panels could be used to cover the striped overhang. Not too difficult to make.
Gloss paint circles (can be any shape) painted over flat paint.
Note the column that is painted with chalkboard paint. Not too classy, but a lot of fun. You might consider this for your big white column.
Whole walls can easily be covered with curtains. For example the wall at the far end of mural part of the room.
Note how this counter top has been cut to go around the column. A narrow round counter top that goes all the way around your white column would serve as a place for folks to stand and rest their drinks. Or add bar stools to function as a place to sit.
