Spider-Man and Nathan

This is a commission for a local girl's nephew on his fifth birthday. This is a week's worth of work. I apologize for a not so clear scan but because I was racing the clock I didn't have time to scan it properly, so a snapshot's as good as it gets. Etched on 9 x 12 Bristol with graphic leads, the situation is Spidey's giving Nathan the grand tour before his birthday party and is about to take him home, but then hears the Green Goblin's laughter in the background...
