I've included a stand of IDF infantry in these photos for scale.
I'm really pleased with how these turned out. The trees are cheap Chinese imports from various manufacturers. The bases were textured with ready-mix paint-thickener before being coated in sand using PVA. I added some Gale Force Nine static grass & meadow flock to the bases, along with the classic lichen clumps for scrub. The rocks are just tiny stones that I've painted. I went a bit far & actually painted some of the large sand grains & shell chips on the bases as 15mm-scale stones... :-s
