Your space is quite roomy at almost 23 feet by 16 feet 5 inches. It would help us to see all four walls. Is this going to be an area where you will eat as well as watch TV? I would put in some recessed lighting: (I like the idea of painting the ceiling a light blue or yellow.) You need to have table lamps and or floor lamps as well. If those are light fixtures on the beam, I would remove them and repair the beam. Would you husband be open to staining the beams darker? Something like this: A fireplace mantel like the one in the Crisp photo would finish off the fireplace. With yellow and cream, you could go with warm colors, browns reds and oranges or blues and green.

Oh so cool you noticed that we're trying to achieve a french country/industrial look or did we write that somewhere? I've attached some other photos of a bedroom and the foyer (of those we've taken so far), but are absolutely open to suggestions on a "beachy" feel as well or instead of. Although because its a beach house we don't want to go over board on expense and hence keeping what we already have, and just adding personality to it, if you get what we mean. Kingsize Black upholstered headboard to come in that bedroom.

Treating the sliding doors as a modern insertion and keeping the rest traditional could be striking. However, what does the house need from the interior? If it needs more light/views opening the house further with larger windows could be great too. An important detail for the sliding doors will be the casing (trim) - whether modern and intentionally different or matching the rest.

There is nothing worse than ceiling-mounted lights--harsh shadows, flat lighting. They are strictly for utility. I would put a large-ish, shallow cylindrical shade on them and put nothing more than a 15-watt bulb in them. Use them strictly for lighting your way as you walk through the room. I agree with Vincent; the chair in the corner doesn't fit at all, nor does the one under the A/C unit (put that one with its mate behind the love seat). And the curtains look smooshed. I think the problem with the bookcases is that they are uninteresting. Did you buy books-by-the-yard? What are all those identical books? They are visually uninteresting. I'd get rid of some of them and get some colorful ceramics/glass/photos. The room is absolutely overwhelmed with furniture. It needs one less love seat. Do you really need all of them? Pushing them against the walls/curtains so tightly just visually emphasizes the fact that there is too much furniture. I don't think a mirror above the fireplace will work. When people are sitting down (which is most of the time), all they will see is a reflection of the ceiling--the plain, white ceiling. Get some real art in there with some color.
