I've always enjoyed drawing kids' faces, perhaps because of their simplicity. They don't have all the warts and wrinkles that come with the aging process! The hardest things to get right are the spaces between their teeth!
And if you notice those ears too, you'll see a striking similarity between the young and the older W! Just a little elfin, methinks!
Sassy, you still haven't told me if you've finished yours and put it up on your fridge!
