Lol! I've been there, from the parent side and the kid side! Great take on the theme and I love the facial expressions! :)
Ohhhhh, boyyyy. I remember that panicked feeling. See, mom is ALWAYS right. Especially now that I am one. Great, great illo!
Although I love the expressions on these kids' faces, I don't think this is one of your stronger pieces! I probably would have wanted to see an illustration that had some more depth of emotion... and with the Volvo pulling into the driveway maybe in the background to illustrate the full story...
Thanks for your feedback!
