For my first card, I used the Dashing Deer stamp set. This is almost a one layer card. I used some masking technique to create the snow banks and the sky. I colored the images using copic markers. I embossed the sentiment using silver embossing powder.
My next card is a bit more layered. I used You Make My Heart Melt stamp. The sentiment is from the Dashing Deer stamp set. I sponged the sky and then applied some embossing paste to create the snow. You can certainly use a stamp and embossing powder to create this look.
Here is a close-up to see all the texture and layering.
