Just finished a 6x4 BATTLEGROUND terrain mat, this is a picture in natural light, as it rest half folded against a bookshelf:
the tank is the usual 1/100th scale (15mm) Zvezda plastic model used also as a scale reference in the pictures of the "Arid" (dry terrain) finish at http://baueda.blogspot.it/2012/12/this-is-new-6x4-in-arid-finish-tank-is.html and "Desert" + "Temperate" examples shown at http://baueda.blogspot.it/2012/09/6x4-180x120-cm-backdrops.html
same as above but with light turned on and a slight contrast enhancement in post processing
and this is a close up which I did using a strong light from behind to show the texture, but unfortunately it did burn out the colors almost completely...
The couple of 36mm figures are from our own 1:48 scale range: http://1-48combat.com/
