The cold never bothered me anyway

Nice drawing! The shadows, borders and colors are very well made, and look just like the original one. It's really eye-catching because it's beautifully replicated and painted.

The combination of all the factors create a very good piece of art, but knowing it was based on a picture somehow subtracts some impact to the viewer.

I can assure you, if I saw this outside deviantArt and it didn't had your signature, I wouldn't notice it's not from a Pixar designer because their cartoonic 3D style is very well done here.

Obviously there is always room for improvement, there are some lines that look too sharp for the smoothness of the picture (like the ones from the edges of the drawing) and I feel the eyes are a little over-saturated, but that has less impact on the quality of the image.

So, my overall for this picture is very high, keep up the good work!
