Very nice! You did a good job choosing the backgrounds, they add a lot to the mood. It's a shame they don't match the character portraits (I would prefer not having the portraits in this case). But I understand time was short, so it's ok.
Thanks for sharing your thoughts! I felt like the character portraits made it clearer to see who was talking when there was more than one person around, but I know what you mean. They are very different styles. Glad you liked the backgrounds though, I purposefully made them all black and white to try to set the mood :)
