Winter post card ideas

I've started working on some images for my winter post card. Really it's the only reliable postcard I get out. So I figured I need to get started if I'm going to get one completed and set.

The theme given to me this year was an alien snowball fight. So here is my first little guy. These are all sketch images that will be cleaned up and finalized once one is chosen.

That said, I'm taking votes on which image to use and send as a postcard. 
And remember, to get a hold of me if you'd like a copy of the postcard.
