Thumper shares a secret

For the Christmas family draw this year I had my grandma. I remembered having a discussion about the Disney movie Bambi with her, my mom and my aunt sometime in the past year and she exclaimed how much she loved Thumper, so I figured I'd make her a painting of 'my' version of Bambi and Thumper instead of a Disneyfied one. Same characters, same personalities as the Disney story, slightly different look. It's a belated gift, but here's the preliminary sketch for it (mucky scan, sorry, no Photoshop at home to clean it up). I'll update with the final in a few days.
