Halloween Portraits?

I have been playing around with Picnik, trying to figure out a way I can get my 6th graders to make a Halloween portrait.  I think it would be super fun...

...if.

If I could arrange for them to all use the premium features.  The free features are not nearly as cool as the premium ones.  I purchased a premium membership for my family, but I don't ethically think that extends to all my students.

If I could make sure they keep their portraits rated G on the gore and violence scale.  There are options that are just too over the top for elementary students.  Blood, injuries, and guts.  However, there are fun fangs, glowing eyes, and other fun (non-slasher movie) things they could enjoy, too.

Here are some portraits I created this evening that range from slightly creepy in a fun way, to down right disturbing and almost scary.  They are all from the same base photo of me.

 Ghost me.

 Creepy-up-to-no-good me.

 Slightly disturbing and headed toward slasher flick me.

Out and out over the top slasher movie she's gonna die me.

Hey, look!  I'm an ogre!  I think the boys in the class will like this one.

So.  I have a week or two to decide.  I'll let you know how it goes.
