FOW SMG Teams started

so I got the first two teams glued down ..then used some hamilton beach sand to and thinned out elmers glue to cover the integrated bases.

The color is really close to the same as the bases that I drybrushed..I still need to dullcote them and add some static grass.

But I'm wondering..think I should be blending in the sand with some brown and linen white paint drybrushed?
I did that for the HMG crews but I just dont' know if its a waste of time for so little difference on the dirt.

anyways opinions always welcome :)
