1/48 British infantry Diorama

Hmmm...I'm not loving the green gravel, Huxy. I'd cover it with some static grass and THEN spray it in various dull greens--that green is also a bit garishly bright.

Otherwise, the first thing people will say is....."is that green gravel?!?"

I say it's more like ground, without high grass :)

 And it's not supposed to be a combat zone. More like an abandoned place in a city...

Green gravel?  Where have you ever seen it?  I'd go with a greyish tan instead... The wall looks good, but rather too good a shape for a combat zone.  I'd suggest using the ol' Dremel and gouge a few chips in the face of it from bullets/shrapnel...
