Redecorating these rooms. Any suggestions?

So, I'd like to redecorate my living room and family room. I'm not going to buy a new couch or anything major. I'm planning on building a new coffee table and end tables when I have some time. I'm either going to make epoxy river tables similar to the one I made in the pic for the living room or something like the the white coffee table in the last pic. I'll probably start on them in a few months.

I have an old piece of barnwood that is about 4 feet wide and like 3 or 4 inches thick and about a foot deep. I was thinking of making a floating shelf with it to put pics or other things on it. I just don't know where to put it at. I could always cut it down to make a few different floating shelves with it.

Eventually, I'm going to build shelving in family room around the TV with an electric fire place.

In the mean time, what would you do? How would you decorate them?

Any advice would be appreciated as I'm spinning my wheels and trying to figure out how to make my house feel more like a home.
