before and after living room

My house is (kinda) clean today so I thought I'd snap a few pictures and show you what we've done in the (formal-ish) living room. First off are the before pictures. (As in, before the house was ours). As you can probably tell, the living room and dining room share one big space. We broke it up by putting hardwood floors in the dining section.

I like how the previous owners had stuff on the walls. I am REALLY not good at hanging stuff on the walls. In fact, I could really use help in that particular area. Anybody want to come over and help me?

I like this chair and the little wall table (belonging to the previous owners), but this is where we keep our piano.

This is our house now (and this is what it looks like as of today). Looking at these pictures totally makes me want to move the bench off the front porch. In fact I may do that right after I post this. It distracts from the window! In this room we painted (lambswool by pratt and lambert, do you see a theme?), we got new carpet, and we changed out the entry way light fixture.

What do you think? I recently rearranged (after the buffet incident), and I think I like it, but I'm always open to others' suggestions. And again, please tell me what to hang on that huge ass wall above the sofa. I know it needs something, I just don't know what!

In case you care about where stuff came from: the sofa is a hide-a-bed (we can have guests!) and the lamp to the left of it are from Bassett way back when my cousin used to work there, the two arm chairs and the round side table are from TJMaxx (score!), the red ottoman is from overstock.com, the piano is a hand-me-down from my aunt and uncle (thank you!), the entryway table was inherited from Chris' Grama Ruth, and the entry way rug is from TJMaxx. The curtains are so old (we brought them from our old house) that I don't remember where they came from, but if I had to guess I'd say they were vintage Target. : )
