Hm... could be I used the wrong word. Meant the German "raffiniert", and it covers a pretty wide range (http://www.dict.cc/?s=raffiniert). In this context it would mean exactly what you are doing... its not just plain simple elegance, but a step beyond... even if it means a hair out of place or something like that.

In my own work I call it "something to scratch the eye a little".. which probably sounds odd too :-/
