I am somewhat (read: not really) ashamed to admit that the person that comes to mind for Morwen is Alizée Jacotey
. (Additional image
I blame Tainted Orphen's bio for linking me to the official music video
for her song "J'en ai marre," and when I decided I liked the music, I poked around a bit and found this
video (same song, from a TV concert or something) where I did a double-take when I realized she more or less matched my mental image of what Morwen looked like -- it was hard to tell in the first one with all the water.
The irony that Morwen is a musician in her spare time/as a hobby (from early on in RP), and that Alizée is a French pop artist, is not lost on me.
