Wow, this character is beautifully made. Really like him, though I couldn't think where I should use him in my project yet. Will come back when I get an idea.
BTW, will you consider make an armored version? Some light leather armor, like a gauntlet or armor piece covering his chest maybe. Right now grandpa doesn't look like he is adventuring with the hero or wizard, but it looks great standing in a blacksmith, barn, or garage.
