@Vinnie: thank you for the kind words, Vinnie. They are most appreciated
Update on the project below. I apologise for the pictures. The photos without flash seem to be a little to dark, while the photos with flash seem to be to light and with too mush contrast between the colours. Reality is somewhere in between. Hope you will enjoy the pictures anyway
I have now given the turret and the engine deck some thin washes around the fine detail. A few details like the tools were also painted.


I have also added the mud to the suspension and the edges of the fenders. I am pretty satisfied with this. The mud was made from a "back to basics" recipe like the rest of the model. Fine sand mixed with a few drops of water, white glue and some black and mud brown paint. The white glue are from a hardware store and the sand is from a pet store and is the type used for pets like mice etc. For around 15 USD you get enough sand and glue to last for 150-200 tanks :-)
The mud mix was applied in several layers with washes of dark brown and black in between. The washes where applied before the mud mixture could really dry. This way it is easier to get a "blending" effect in the mud and it does not look painted. Finally a light drybrush where added to show dry mud and bring out the texture of the mud.

Now it is on to some more weathering and adding of markings. Cannot really decide how to mark it
Thank you for looking. Hope you enjoyed it. Comments are most welcome
