Thanks, Joe!
I didn't took photos of the progress, but the base is quite simple:
-picture frame 15x20cm;
-ground is tile grout Keracolor, it's colored-beige, leveled with spatula, and after that some foot and tire prints;
-various acrylics when dry-light brown, sand etc.;
-desert tufts and rocks here and there;
-palm trunk is from wood branch, bark removed, cut with modelling knife and painted;
I've made similar base for my Alamein Sherman here:
