Put a piece of tracing paper over the drawing and put lighting where you think you would like it.

Recommendations tend to place them about 18-24 from the wall so the fall onto the counters. That would give you a row down each side of the kitchen.

Then you can do fixtures down the center of the island of recessed and pendant.

Once you see where you want them, then align them with each other and set up a grid so they are not random. This may mean that if one is centered over the cooktop, it may end up that one is not exactly centered over the oven or fridge A opposite. You will want to center over the primary points of interest and go out from there.

This is a way to start anyway.

I love that pumpkin pendant! My personal preference is not to have recessed over the island, but I think I'm weird in thinking that way. Because the style of pendant you've chosen doesn't have a solid bottom you might be able to get away with not putting recessed over the island unless you want it. My two pendants on my 6 1/2 foot island provide plenty of light. They are also two bulb lights and the max wattage is 120 for each pendant. Can you check the max wattage for those pendants and install 3 pendants...can't tell how large they are or if 3 would be too much for the space? Because of the glass they will give a diffused light rather than the directed light that a can will give you, but even with my pendants which cast a weird light pattern I still have plenty of light and don't feel like I need the recessed over my island.

Good luck!
