Snowboarder

Metaphor: 

the snow was white puffy clouds.

The snowboarder was a polar bear wild free.

The trees were covered in a white blanket as if at any moment they would fall into a never ending slumber.

Simile : 

the wind was howling as loud as a wolf at midnight. 

The trees were as white as a a wooly sheep. 

The sky was like a heavy snow storm.
