Here it is, I've finished! :-D
I'm pretty happy with the results. This Brioche stitch goes pretty fast and the texture is so soft and fluffy, I guess that's why it is called "brioche".
Anyway, I'm thinking about adding one or two knitted or crocheted flowers to the edges of the scarf, just to make it more feminine, but I'm not sure my friend Claudia loves "girly" accessories ;-)
