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 ghost chairs are AMAZING! Very strong and stable. It brings a a lot of space for a small room and the loui style are very classy. Ok I will buy the table, it's goof price and I totally love it. I am living in a construction camp at the moment! Everything is a mess but I hope everything will look beautiful when the renovation finishes. I have just moved in with my partner, the typical manly man and I am the typical burly so it's hard to compromise in colours and styles! Plus there aren't many cost effective options in NZ so decorating is basically a mission!

I say yes, it is! I can relate 100%. We are building a new home, and I've been doing most of the selections & meetings. I've been looking at paint chips, rugs, fabric swatches and furniture until I'm blue in the face. I think it's ok to take a step back and not have every last loose end or finish choice buttoned up immediately. Give yourself permission to take a mental break from it and come back to it later. Good luck!

So far so good with the furniture and wall color choices. Feels a bit towards 'rustic contemporary'.
