Don't forget to add some abandoned equipment etc. make the scene look 'used' as if the Germans have put up a bit of a fight defending the place, they would have thrown down their weapons in front of them too.
The sherman looks excellent, as does the SAS jeep. can't see enough of the horch? to comment, however, i'd say a couple of washes wouldn't go amiss, same for the figures, some variation in the fieldgray uniforms would stop them looking, well, so uniform!
Hat's off to you with the base and farm I must say, they are very impressive. Love the rocks in the field too.
Keep up the good work,
James
