Been researching more ideas for the Halloween-specific designs (for boys especially).
Here are some links that I came across, hopefully they will help:
Pumpking design - Very cute, I totally will have to practice that. Good for girls AND boys. And the cool thing about pumpkins is that they can be cute, happy, or scary. Its a good all-around vegetable.
Bella Sugar - Featuring 5 interesting and elaborate designs. The first image (the cute cat) is Angie Anders of Face alive. She is a really nice and talented face painter that I met over at the forums.
If you have links or sites, or tutorials that you have made or know of and would like me to include on this list - please leave a comment.
