Yes, looks very nice :) I will comment on lighting, sink and lack of extractor fan.
Switches and sockets! If you are doing everything from scratch including new electrics, then think long and hard about where do you want light switches and electrical goods (coffee machine/mixer/etc.) Again you need to visualize using appliances and switching lights on/off. I would have 2 light switches - one by the entrance into kitchen and the other by the door into garden.
Lighting wise - those two lamps on the sides of display cabinet will not be sufficient. In my kitchen I have spotlight bar with movable arms and movable spotlights. I really like two hanging lamps over breakfast area, so your solution to better lighting might be small fixed built into ceiling spotlights.
I also have a sink under window and my main problem is that splashes get onto windowsill, however I do not see where you could move it.
I noticed you do not have kitchen extractor fan?
