I'm glad you like them. It was nice to see how much of the art is done for the sprites and bedrooms assuming they stay that way. Jean having chemistry, physics, and engineering whiteboards is nice to see since she won't be as dumb as Forrest Gump.
As for Kurt's accent, W=V and V=F is basic German, so I would say it would depend on the word and how German-like it is for the V one. I'm a little surprised J hasn't entered the conversation, but I guess it is a rarer letter.
Edit for one last comment: The two German exchange students I have met didn't talk with these stereotypical accents.
