The figures for the 375 castle were designed by James Sutton, another Brickish member in the UK. I had my doubts that figures at this scale would ever look totally believable, but I think you will agree that these do.
James has also made LDraw files and I think that it is his plan to make them available to anyone who wants them at some point, so I expect to see many of minfigs at this scale in the future!
Well done James, I will certainly be making some very soon. They are sooo cute!

Check out this picture to really get a sense of the scale of it! (The original size set is on the table to the right).
I was lucky enough to get to help build and take this apart at the Brickish AGM in Sheffield at the weekend. It really is amazing how big this is and you know it is a big LEGO model if you need to look up at it! I always wanted to know how what it felt like to be a borrower :)
The attention to detail is amazing, even the drawbridge can be raised and lowered. I will talk about the figures in a separate post or this will get too big.
Congratulations Duncan, this certainly raises the bar in terms of scale building and part of me just wants to give up now as this is way out of my league!
