Spider robot winter scene

So I have added materials and made some changes to the hills in the scene.
Not really sure what colors I should use and like a trillion other minor details.
I am not really sure if people realize the size of the spider-bot and that it is
using a micro-ski, so I need to establish scale in this scene without adding to much stuff.

Work in Progress.

So a while back I modeled a tiny spider-robot. I have been thinking of using it as a focal element in my images to get them more interesting. Anywho, I was thinking of doing this when the weather got all snowy here in Sweden, but there has been mostly raining. So got tired of waiting for snowy inspiration.
I think I need some minor alterations on the hills and then it’s off to adding materials.
