I'm not feeling the tall windows at each end. The dining area can get a light of your choice depending on furniture style. Remove the other.

Neat space! What feels awkward to me is how small the dining room space is relative to the cavernous living room (which runs the risk of having a lot of dead space based on how the rooms/passageways are situated). It’s hard to get a sense of how big your overall home/flat is from the plans, but I’m wondering if it would make more sense to have your dining area be in the middle space of the living area, i.e. between the bumped-out window and ‘lobby’ areas, which might then allow you to repurpose the existing “dining” space as a study/ office or additional sitting area. This might help to break the space up a bit and make the furniture arrangement feel less awkward. Just a thought but hopefully some designers will weigh in!
