A Slightly different approach with the Devastator Squad Sergeant. Only dusty on the lower legs, and a light drybrushing on the backpack.
Not sure how well I did the face and hair. I think it came out alright.
No rocks on this base, rather three clumps of grass.
So that is the Devastator Squad complete. Below is a picture of the three Space Marines on the desert sand bases.
And finally the whole Squad.
It would have been nice if I had all of them on the same base design, and all with similar weathering, but I think this is a good group all the same. I have another full Tactical Squad of Space Marines, so I will do some more experimenting with them.
