Here's an step-by-step update on the ground work of the vignette.
First I masked the frame and painted the whole thing in a mix of Beige and English brown acrylics, so that the white color wouldn't shine through.
To get different texture on the desert floor I used three types of sand.
No 1 is real fine sand, brought home from the Canary islands.
No 2 is ordinary hobby sand, with bigger pebbles.
No 3 was bought in a pet shop, and is normally used in fish tanks. This sand has the advantage that the pebbles are of different sizes and also color, giving the desert some much needed variation.
Three small stones was glued to the base before the sand came on.
After covering the whole thing with white glue, I added the sand, and tried to break up the uniformity by mixing the sand in different proportions on differing parts of the ground.
After that it was time for the base paint. I used a mixture of Vallejo beige, red, yellow and pale sand, trying again to get some variations, with shady and highlighted areas.
Then I added some more shadows with very diluted oil paint: Burned umber and Yellow ochra. The three white stones also got a wash.
Then I sprayed the whole thing generously with matt varnish, and added some more no 3 sand, especially around the contours of the dug in tank. When it had dried I put another coat on just to seal it.
After that it was time for the pigments to be added, both in order to do achive some highligting effect and to blend different colored parts together. I used MIG Beach sand and Light dust. Here's the finnished result on the ground work.
And here it is with the turret in place.
Now it's time to fill out the vignette with some equpiment and maybe some dead vegetation, to further break up the monotony.
Yesterday I also ordered some 2 pdr spent casings in brass that I will add later.
That's all for today!
