I have 2 of the 3 models panel lined for my GBWC project, but have been fighting some burnout lately. I took a break for part of this weekend, while still making a bit of progress. I have a little less than 2 weeks to finish, which should be ample time, but I need to balance making steady progress without pushing myself too hard and burning out.
Regarding Setsuna:
spoiler
He sees Gundams as symbols of hope and peace, rather than just giant super-robots, so he wants to embody what they represent. In that regard, yes, he is a Gundam.
