Personally I think your dining is crying out for a bigger statement, something more luxe or at least larger, either single or many pendants hung together even. At different heights. And I disagree - you can make a different statement with the dining area that does not follow the lounge theme. Whilst they flow they are still separate areas. Just my opinion!

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!

Though I don't know for certain, I think the cotton/linen shades are removable. I wasn't able to determine this by my searches. This could easily be confirmed by making an enquiry to supplier before purchase. Alternatively, a handmade one could be made removable by making shade slightly larger than frame and making ties.
