STL Hat & Hand Fixes ($30 To Fix)

I have an STL character model that needs two quick but precise edits before I send it off for printing. First, the hat: the basic shape is fine, but it looks plain. Please sculpt in extra surface detail—think subtle seams, panels, or other small touches that give it a finished, believable look...
