For starters your T.V. is way too high lower it to sit virtually on the mantel and take all the stuff off the mantle. If you are getting storage built get 2 made so one on each side of the fireplace for balance. I don't see what you have for lighting now and find the finish on the walls very busy. When I look at your idea books I am not really getting that same feel in the space as it is so maybe some more pictures would help with that.

if you're not going to center the dining room table under the light, then I'd tend toward a flush or semi-flush fixture, to de-emphasize the alignment. You might want to remove the medallion from the ceiling too. As for the kitchen it looks like you have decent overall lighting -- maybe you're looking for a couple of pendants over the island? simple glass globes, maybe? here are a few styles to start you out.

My light casts it's frame shadow, but it's not that noticeable because it's way up high (see pic) mine is in a double floor height ceiling. I think if the pendant was lower, then shadows would be more prominent. Also, my light isn't as busy, so the shadows are less. Overall, my take is the busier the pendant and lower the height, you'll see more shadows. (don't mind the paint job, still in reno)

Can't decide whether to mirror the wall above the loo and sink area or put in wall hung mirror with light fixture above ... or buy a hib mirror with built in light? Any advice??
