Well a cool idea may be putting all your characters in one big pic. Or maybe having some sort of celebratory scene, with much going on. I don't know... its up to you after all, and hope my ideas help in any way...

Draw a Big family of your char

When your friend playing joke on you,
Your friend say' No jokes No fun!'
When your friend see lazyness on you,
Your friend say' No study No future!'
I Turst your True Friend will Care For YOU!

Ignore everyone else. This will be awesome:

Aiden eats everyone, and gets really really huge, then explodes. I will benefit the most from that so you should not hesitate to do it.

The afforementioned was a joke.

Why dont you wait for everyone's ideas, and then make a super picture incorporating all of them?

Kissy kissy makes me happy, honey, honey, sweet as candy
Kissy kissy take my hand, and come along with me
Kissy kissy makes me happy, honey, honey, sweet as candy
Kissy kissy love is grand with you, my sugar bee.

A sequence of some sort, I think its a good way of commemerating; with a series of pictures.

I second that.

I'd agree with the majority. All your characters together lookin' all cute and whatnot. Making them all fat is always a plus.

DO NOT CHALLENGE THE GATE.

Draw him after he's been forcefed 100 cakes...or elephants.
