The detail and composition are fantastic, really! Congrats on the award; that award in particular is a hard one to come by!
The only thing I could think of suggesting is to watch how heavy you drybrush the flat spots, like the trailer's fenders, the Tiger's gun barrel, etc. You seem to have a lot of paint transfer there that unnaturally filters the base coat and kinda obscures it, IMO.
Other than that, great camo painting on the figs for the most part, and I agree about the outstanding trees--what the heck did you use for them? I've never seen trees like that.
