Thanks for all feedbacks! I'll try to respond to some comments.
calvin, I'm glad you like the dio's. My favorite is also the op. varsity. But I also like the Sniper with decoy.
stikpusher, which dio you think figure placement are too tight? Probably the British Ariborne because of very small base. Talking about tight figure placement, I'd like to show my fovorite one - a former work from Joh - which I named "Crowded Square". On 4x4" or 16 sq.in base, he place a 13 figures on it, and it looks good to me. You'll never find a more populated dio, square inch by square inch, anywhere else:
Skonch, I also think the Kursk dio is nicely done. No doubt it's your favorite.
aj, only criticisms, no suggestions? Can't you think of a positive side of these dio's - like having the chance to see many new figure sets built for the first time? They may not be perfect but I think "Joh" has tried his best. Among all my modelers he's the only one living entirely on modelling.
Kelly_Zak, the first dio is not out of place. It's as PaintWithBrush pointed out - that's two separate scenes on the same base, divided by space. And all tanks are not part of any dio, I used them as backdrop or complimentary pieces only.
PaintWithBrush, yes, you're right. You have such keen eyes. I also like the Russian Sniper with decoy. Now Joh is working on German Sniper Team also from Zvezda among others.
