Do you not want to have a ceiling fixture there at all? You could do a wall mounted light above or to the right. If you are concerned about task lighting, I would go above and I think a task light like one of these mixes nicely with the other schoolhouse lights

If you are not as concerned about task lighting at the sink, I think a sconce between the dutch door and the sink would be awesome.
If you were doing a ceiling mount light then I think you could do a schoolhouse over the window, either semiflush or rod mounted like these pictures.

Due to the fact that we both have post and beam, lowish ceilings I posted a similar thread not too long ago, I am attaching the link in case it is helpful.

Here is a link that might be useful: To light my sink

Get a small surface mount that coordinates with your other fixtures.

I like the first picture that localeater posted. They blend nicely with the school house lights. My other suggestions would be the school house style light in a semi-flush mount.

How about a swivel arm wall mount ? That is what I did for task lighting on either side of my brick chimney. I love it and it gives great light right where you want it. c

I wanted to put a multi-light sconce on the wall above my sink. (My KD talked me out of it, arguing it would look too "bathroomey.") May work for you.

I like the look of wall mounts swing arm type lights like the ones localeater and trail runner posted. Should I do 1 light or 2? The other lights in the kitchen are 2 flush mount school house lights from schoolhouse electric like the one below which are centered on the aisle. I still have to get something above the table near the windowseat.
