We would ideally like the dining table to be moveable between either end of the dining area depending on party size!
That's an inhibitor.
This basic type of lighting:
can look good over a dining table, but not much good if you move the thing around.
Avoid small downlighters like the plague.
In the kitchen area I'd suggest minimalist, unobtrusive recessed ceiling lighting (large diameter though), dimmable would be a good idea so you can have some light in that side of the room when eating.
Concealed under cabinet lights would be useful too.
What are you doing about an extractor over the island hob? You can get
these.
Concealed neon lighting?

You need to start looking online, and going round proper lighting shops (not the sheds).
A few non-lighting suggestions:
1) You should seriously consider a wider gap between the island and the worktop/units along the wall - it looks like it's under a metre, which will drive you bonkers if there's more than one of you working there.
2) I can see how stalls there would save a lot of walking back and forth to the loo when you've had a few, but it's not very hygienic, and the womenfolk won't like it, no matter how many photos you find on the Internet.
3) A cantilevered canopy like this:
would be a jolly useful thing along that wall with the folding doors - we quite often have weather where you might like the doors open even though it's raining.
