Thank you! The lichen and the buildings were nearly all Mike's, and the rest is mine.
Sadly not, no. I got rid of my 20mm figures about three years ago to move down to 15s... and here I am playing with 28mm models just because it's the club standard!
Luckily Some Corner of a Foreign Field doesn't need many models, just a squad per side. I wouldn't do 28mm otherwise, it's very much a skirmish scale for me.
