With a long room like yours, I would recommend thinking about how you will use the different 'zones' of the room - so for example you may want something soft above the couch, enough to read by but also enough to relax under with a glass of wine in the evenings whereas over the table you may need something brighter for the kids to do their homework (or whatever your lifestyle lends itself to). Where possible I always recommend LED lighting - they are capable of producing both warm and cool light colours and can even be used in accent lighting. They are also very popular for their energy efficiency and they give off almost no heat which is an added safety feature.

Certainly a unique light!

So, what color did you eventually choose? I am really interested because the house we have just bought has similar color ceilings. I was also wondering about the color of the light fittings. I think that I will get some color changing LED light bulbs and have them installed all around the house. I like them more because you can both use them as a regular bulb or change the color to any you would like. It is also possible to control them using an app on my phone, making it so easy to control them. Now I think that it would be the most reasonable decision if I installed white bulb fittings so they look good with all the colors the bulb can make.

I would definitely remove the animal on the floor and cushions. And the Italian pedestal and floral display. Try the deer print on the black wall in the lounge area. Try it on the right hand side of wall at eye level, after you take the pedestal away. Put your tall table decoration onto the white buffet, where the deer was. Can you remove the shiny light fittings that are in the dining room space. They seem not to work. Install led down lights. As the existing lights seem not to be where you have your table. This is my opinion. Everyone's tastes are different.
