WOW Iceman have just accessed this thread for the second time but I confess the first time i did so was on my phone. At first sight (on a small screen) the images didn't do justice to your terrific diorama. However, now on my PC your work comes to life and really is much more impressive.
From the mixing and matching of different manufacturers, your extremely impressive basework, to your painting of body paint and finally the photography i love the whole thing.
If i had to find fault I think that after such impressive defensive earhworks were put up one might have expected a greater density of defenders - in which case you would have needed more Romans to make an attack viable. Put plainly I think I'd have loved to see more soldiers scrapping it out!
