That looks so cool! Such an underused scale, I think it is because Lego doesn't really do anything at that scale right now. If I remember right though, there may have been some cars released around 2010 at 12 studs wide? Can't remember.
Exciting...
Been such a strong field this year, I really think some of these designs are some of the best MOC's I've ever seen. The TIE Defender and the fallen AT-ST are some of the best IMO, but I have also really appreciated everyone's creativity with the custom ships and locations.
