What a fun space! Love the pillows...I agree with above, lower all the frames, but not so low little ones can reach. The art should fall at eye level about 5'4" for walls and for behind the sofa not more than 12" above it. Then keep the width about 5" inside the sofa length on each side. Your frames are small so you need the close together for impact. I would start with some pretty curtains for the door and large window and then a simple Roman shade for the small window- since your girls play there you don't want anything they will grab hold of. http://www.houzz.com/ideabooks/query/how-to-hang-a-photo-gallery

The wall opposite the couch could hold the TV - would need to mount it on the wall and that would take a while as we would need to get someone in to do it (I love my husband but he's not the handiest). Where the photo was taken is a three seat couch, so couches are in an L shape.

As you rethink adding a fixed window, consider either a fixed window that is the long horizontal kind over the shower/tub surround and/or an octagon one with stained glass for the dressing room. https://www.google.com/search?q=images+for++octagon+windows&biw=1366&bih=673&tbm=isch&tbo=u&source=univ&sa=X&ved=0CCIQsARqFQoTCOaJ69fb28gCFcYVPgodogsLDw You could add a couple of pairs of shutters to create a pair of faux windows that look as if the shutters are closed. If you don't want a window that opens on that wall, you might consider having a fixed window and shutters that are louvered to let in some light while protecting your privacy. You might also consider a faux gable with a faux window, perhaps functional as part of the venting system for the bath.
