The look really good
What colours did you use for the bases?
Thanks for the kind words. I found the sand recipe a while ago, and so can't take credit for it, but here it is;
(All colours are Vallejo)
Base = US Field Drab
1st Drybrush = Cork Brown
2nd Drybrush = Tan Yellow
3rd Drybrush = Dark Sand
Final light DB = Pale Sand
