Assuming you mean you are putting two pendants over the island. That is a lot of fixture and light for a small island, especially with the overhang at the end. At 12” each, you need a fair amount of space between them to have an impact. Is the counter wide enough to handle the two?

As for a chandelier, nothing too out of the ordinary; something in the same style, but not shape, as the pendants .

How big is the table? The chandelier should be about one half the size of the table.

Great looking kitchen space! Are those pendents about 12" wide? if so you would want to hang the pendents about 26" apart from each other and about 30" to 36" above the top of the island.

A chandelier like the one JudyG posted Is the right style!! It has soft curves and simple that will help complement the pendents. I would not do anything too boxy. For a 42" round dining table, I would do a chandelier that is 22" to 28" wide, and would hang it about 30" to 32" above the table. Here are a couple of styles and sizes. Good luck!
