Hello Kurt, outstanding simple layout, congratulations!

I like the ground work, especially the grass, rusted drums, and also the dusty cobblestones. But I'm curious about usage of yellow as the basic color of such drums, IMO somewhat unusual, although it may possible to be applied. How about neutral grey or it's deviations? Looks more natural, but that's just my suggestion. Also for the tools mounted on the Panzer's fender, several of them have their wooden handle, you may apply them with wood brown color. It may be suitable rather than the flat black you used.
Overall, again, it was a lovely scene and you have to show your another outstanding project mate! Thanks for sharing
Kind regards from Indonesia
