The TS1500 door closer is what we seem keen on for our door pictured on my Flickr page, though I’m a little worried it will be an eyesore:-

A TS1500 is a good choice and can be dressed up with a matching cover & arm in polished brass for example.  Having a close look at the photo, we would like to suggest perhaps fitting the closer in the “Figure 66” position on the other side of the door.  This is because there is not very much space between the door and the wall (where the African head is) so the door will not open to 90°.  Also the top rail of the door is not very deep.  You can see what we mean by “Figure 66” by looking at this page link.
