Hey, and welcome to 40kO.
Your Chaos Marines are pretty sweet, I love the colour scheme. My only complaint would be that the metals are a little too bright, but it's a matter of taste I guess. I love those snow bases, I've never even dared to make anything similar.
Overall, good work and I look forward to see more of your minis (especially on how the scheme and snow effects translates onto vehicles).
