Best friends forever

This is a drawing I did for a dear friend who's cat passed away a few months back. After seeing how heart broken she was about the loss of her cat Snuggles, I thought I'd surprise her with a drawing of one of her favorite pictures of them two together.

I used graphite pencils 4H-6B, illustration board, blending stumps, tissue.
The piece is 18x22
Total time to complete 70+ hours
