I have a Siamese (well, I think; she looks like one but I don't know anything about cat genetics).
One thing I think is interesting is that, when she came to us, she looked very much like your picture. The older she got, though, the more the dark coloration from her nose migrated and spread.

Now she looks like this. (Please try to ignore my disheveled hair. A recent surgery has reduced my opportunities to shower.)
edit: My wife likes to describe our pets by their apparent flavor. Ripley, shown above, is s'more flavored. Another cat, a striped one another lemming once described as "standard issue cat," hasn't been given a flavor. Instead, because she has one white toe, she "stepped in milk."
