Living Room Revitalization

My poor husband.  Every few years I get tired of certain rooms and completely redecorate.  We've lived here for four years, and I'm still trying to find my groove.  The living room was the most recent victim.  So far I've purchased two new floral side chairs (marked down to $179.99 from $229.99 at World Market), brought a pedestal side table in from the office, found throw pillows at Target and Etsy, purchased a new rug on sale from Overstock, and bought 2 16" x 20" frames from Etsy to go between built-ins and windows.  Here is the layout that I've been envisioning:

The back wall is all windows and a door to the backyard.  The front left corner is where the built-ins meet.  The front right side is open to the dining room/foyer. 

We still need:

-two leather couches
-new coffee table
-mount TV above fireplace (mirror above FP is moving to E's big girl room)
-two chicken man (Ernest Lee) paintings for above the paino

We love our Haverty's sectional, but it is too light in color for a two-year-old and a golden retriever.  It's had a five year run, and is so comfortable that two of our good friends have purchased the same one.  We machine wash the cushion covers about every two months, but it should be done once a week.  They get gross from little grubby fingers!  I need something that will just wipe off and be able to stand up to childhood.

What do you think of this?
