Deep snow! (My First Space Wolf)
I see many snowy bases with bare rocks jutting out of them. But unless the rocks are really steep, that's just not how snow works: it should cover everything!
So for my first outing I wanted to create a realistic "fresh powder" base. I don't know that I got it perfect, but I'm pretty pleased with the attempt.
I actually bought two different kinds snow basing materials, but in the end neither of them gave me what I was looking for. So I just used green stuff (pale blue under coat with a white overcoat). The snow on the cork rocks is just carefully placed speckles of white paint.
