Hi all!
I continued with applying oils. The right side, the back, and the top were missing.
Here is the right side before / after:
From the back and top sections I have only "after"s:
With this, the vehicle itself is basically ready. Next up: figures.
First I used light gray primer.
Then the white was sprayed from above in an angle, so the gray primer is also acting as shadow.
Eyes, faces, details painted.
After covering everything with a gloss coat, I applied pinwash with a dark gray shade to emphasize the details. Also added some brown dots here and there, and blended with a dry brush to imitate dirt.
I leave them like this for a day or so, and then I seal everything with a flat coat.
So, here is the beast with the crew (still glossy):
I want the base to be - partially - covered by snow. I was looking for a cheap material in our household and ended up with flour and baking soda. I made some tests on the belly of the tiger.

Here you can see the baking soda on the left, the flour on the right.
The first row is a sample of mixing the "snow" in thick wood glue.
The second is mixed in thin wood glue.
In the third I applied the thin glue first, and sprinkled the "snow" in it.

It is already visible, that flour is a bit yellowish. It is also a bit uneven, using a sieve would result better distribution, but would be less controllable.
The second thing you can discover, that baking soda can be dissolved much better.
After drying for a couple hours I removed the excess with a vacuum cleaner.

For me, the baking soda is the winner in all three categories.
The thick mixture looks smoother, the thin needs no comment, and the sprinkled sample looks much more like fresh snow.
I plan to use a bamboo board from IKEA. I don't know yet whether I should paint the sides black, or keep the bamboo visible. What do you think?
As always thank you for reading the whole stuff, asking questions, leaving comments, or just stopping by!
Cheers,
Attila
