Hey Eric,
A nice scene you have here.
Firstly, great job on the base, I don't think the transision between road and dirt is too sharp, as a good bit of rain would soon clear up the road surface and make it stand out. A little foliage or some debris would add some interest to the base though.
The figures are excellent, a great paint job you've done there, as for the dirt on the figures, a little more wouldn't hurt, but this early in the war many of the soldiers would be wearing brand new clean kit anyway.
I am building the same trumpeter H '35'/38 (it can't actually be a 35 model due to an incorrect engine deck) and could reel off a massive list of alterations that need to be done to the kit. However, it looks good, you have done a great job with the camouflage and so I won't get into that.
One last point, as for the title, the scene really doesn't look like the Ardennes to me, thinking it to be more forrested, although i'm sure you have a better idea than me!
Great work, thanks for sharing,
James
