While I did enjoy the tutorial, I changed a couple of things.

 Firstly I didn't use white paint on anything but his eyebrows and splatters of snow. I used the white of the paper and very roughly painted in the highlights using indigo.

 I also painted in an open mouth as I felt the bottom lip too big compared to the top lip, hope you don't mind. 

 I'll use him for my tags and cards.
